However, traditionally, validating a design involved the fabrication of multiple physical prototypes. This was a costly, slow, and often wasteful process. That's why, today, <a href=\"https:\/\/www.solidworks.com\/fr\" target=\"_blank\" rel=\"noopener\">SOLIDWORKS<\/a> Simulation offers a strategic alternative by using Finite Element Analysis (FEA) to virtually predict a product's mechanical behavior. Furthermore, by integrating stress and fatigue analysis during the CAD phase, engineering teams can reduce their reliance on destructive testing. Consequently, they can optimize their production costs.<\/span><\/p>\n<h2>TL;DR<\/h2>\n<ul>\n<li>La FEA (analyse par \u00e9l\u00e9ments finis) de SOLIDWORKS Simulation pr\u00e9dit le comportement m\u00e9canique d&rsquo;une pi\u00e8ce avant de fabriquer un prototype.<\/li>\n<li>L&rsquo;analyse statique valide la r\u00e9sistance aux charges ; le coefficient de s\u00e9curit\u00e9 rep\u00e8re le sur-dimensionnement \u00e0 all\u00e9ger.<\/li>\n<li>L&rsquo;analyse de fatigue (courbes S-N) estime la dur\u00e9e de vie sur des milliers de cycles.<\/li>\n<li>L&rsquo;associativit\u00e9 CAO-simulation met l&rsquo;\u00e9tude \u00e0 jour \u00e0 chaque modification : on it\u00e8re vite et on passe de dix prototypes \u00e0 un seul.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\">1. Understanding FEA in the SOLIDWORKS Ecosystem<\/h2>\n<p class=\"wp-block-paragraph\">Finite Element Analysis (FEA) is a numerical method used to simulate real-world physical phenomena. More specifically, in <a href=\"https:\/\/youtu.be\/mRNcyUzNvw4?si=uvLh-UWHMih1ucur\" target=\"_blank\" rel=\"noopener\">SOLIDWORKS Simulation<\/a>, a part or a complex assembly is discretized into a \u201cmesh\u201d composed of millions of small geometric elements (tetrahedrons or hexahedrons).<\/p>\n<p class=\"wp-block-paragraph\">Besides, as highlighted by the <a href=\"\/en\/ohmycare-package\/\">SOLIDWORKS technical experts<\/a>, the precision of a simulation is intrinsically linked to the quality of the mesh. Furthermore, by solving algebraic equations for each individual element, the software reconstructs the overall behavior of the structure under mechanical, thermal, or vibrational loads. Thus, this approach allows engineers to identify areas of stress concentration well before the first prototype is machined.<\/p>\n<h2 class=\"wp-block-heading\">2. Static stress analysis: Your first line of defense<\/h2>\n<p class=\"wp-block-paragraph\">Linear static analysis is the foundation of virtual validation. In other words, it allows us to determine if a design will withstand expected loads during its lifetime without permanent deformation or rupture.<\/p>\n<h3 class=\"wp-block-heading\"><span style=\"background-color: rgba(0, 0, 0, 0); letter-spacing: 0.24px;\">Optimization of the safety factor (FoS)<\/span><\/h3>\n<p class=\"wp-block-paragraph\">Therefore, one of the most common inefficiencies in engineering is \u201coversizing.\u201d So, out of fear of failure, the <a href=\"\/en\/startup-becomes-industrial-sme-with-solidworks\/\">designers<\/a> often add excess material. This also increases weight and manufacturing costs. However, by plotting the factor of safety in SOLIDWORKS, you can identify \u201cdead weight.\u201d These are areas where material is underutilized, and you can eliminate it without compromising structural integrity.<\/p>\n<h3 class=\"wp-block-heading\">Validation of complex assemblies<\/h3>\n<p class=\"wp-block-paragraph\">Unlike manual calculations limited to simplified geometries, SOLIDWORKS Simulation handles complex interactions such as:<\/p>\n<p class=\"wp-block-paragraph\">\u2013 Non-contact between components.<\/p>\n<p class=\"wp-block-paragraph\">\u2013 Tight fits (shrink fits).<\/p>\n<p class=\"wp-block-paragraph\">- Virtual connectors (bolts, springs, welds).<\/p>\n<p class=\"wp-block-paragraph\"><span style=\"letter-spacing: 0.24px; background-color: rgba(0, 0, 0, 0);\">Furthermore, to master these advanced modeling techniques, you can consult the technical guides on <a href=\"\/en\/solidworks\/\">Ohmycad<\/a>, which offer specific workflows to optimize the definition of your contacts and connectors.<\/span><\/p>\n\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/ohmycad.com\/en\/shop\/\">Discover our solutions!<\/a><\/div>\n\n<h2 class=\"wp-block-heading\"><span style=\"letter-spacing: 0.24px; background-color: rgba(0, 0, 0, 0);\">3. Fatigue Analysis: Predicting Long-Term Durability <\/span><\/h2>\n<p class=\"wp-block-paragraph\">Furthermore, a part may perfectly pass a static stress test, but fail prematurely after 10,000 usage cycles. This is the invisible danger of material fatigue.<\/p>\n<p class=\"wp-block-paragraph\"><b>The role of <u>curves<\/u> S-N<\/b><\/p>\n<p class=\"wp-block-paragraph\">Indeed, SOLIDWORKS Simulation utilizes advanced material data, particularly S-N curves (Stress vs. Number of cycles), to estimate a product's residual lifespan. Drawing on technical documentation, the integration of fatigue testing allows for the simulation of complex cyclic loading environments, essential in the aerospace and automotive sectors.<\/p>\n<p class=\"wp-block-paragraph\"><b>Product recall reduction<\/b><\/p>\n<p class=\"wp-block-paragraph\">So, by simulating ten years of use in just a few hours of calculation, you eliminate the risk of premature failures in the field. This is where the authority of your engineering process is built: delivering a product guaranteed against predictable wear and tear.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n<h2 class=\"wp-block-heading\"><span data-fusion-font=\"true\" style=\"font-size: 48px; letter-spacing: 0.24px; background-color: rgba(0, 0, 0, 0);\">4. Why CAD-Simulation Integration is a Competitive Advantage<\/span><\/h2>\n<p class=\"wp-block-paragraph\">Indeed, the major advantage of <a href=\"\/en\/solidworks\/\">the SOLIDWORKS ecosystem<\/a> is its complete associativity. If you change a wall thickness or a fillet radius in your CAD model, the simulation study updates automatically.<\/p>\n<p class=\"wp-block-paragraph\"><span style=\"letter-spacing: 0.24px; background-color: rgba(0, 0, 0, 0);\">\u2013 <b>First, a rapid iteration<\/b>Test five design variations in a single morning.<\/span><b>Second, a cost reduction<\/b>Moving from ten physical prototypes to a single \u201cfinal validation\u201d prototype can save tens of thousands of euros in tooling and materials.<\/p>\n<p class=\"wp-block-paragraph\"><b>\u2013 Finally, a boosted innovation<\/b>Simulation gives the confidence needed to experiment with innovative materials or bold geometries (like topological optimization or lattice structures).<\/p>\n<p class=\"wp-block-paragraph\">So to deepen these skills, explore specialized training resources on <a href=\"https:\/\/hub.ohmycad.com\/knowledge\">Ohmycad<\/a>, your go-to platform for CAD expertise and software optimization.<\/p>\n<h2 class=\"wp-block-heading\">Conclusion and best practices<\/h2>\n<p class=\"wp-block-paragraph\">In conclusion, adopting numerical simulation is no longer an option for <a href=\"\/en\/discover\/\">high-performing consulting firms<\/a>. To successfully transition to a \u201cZero Prototype\u201d strategy, keep these best practices in mind:<\/p>\n<p class=\"wp-block-paragraph\">Check your boundary conditions: A simulation is only accurate if the applied constraints and loads reflect physical reality.<\/p>\n<p class=\"wp-block-paragraph\">Correlate with reality: Use data from your latest physical tests to calibrate your virtual models for your future projects.<\/p>\n<h3 class=\"wp-block-heading\">Optimize your workflow today<\/h3>\n<p class=\"wp-block-paragraph\">So, reducing prototypes is a strategic decision that requires the right tools and sharp expertise.
