This video explains how SOLIDWORKS Simulation replicates physical strength and fatigue tests to predict product performance under real-world conditions. It covers setting up static and fatigue analyses, applying loads, and interpreting results to identify weak points and optimize designs. By simulating stress cycles and material endurance, engineers can forecast product lifespan and prevent costly failures without extensive physical testing. The process ensures compliance with safety standards while reducing development time and costs. Using simulation for strength and fatigue analysis empowers businesses to create durable, reliable products and achieve faster, more efficient design validation.
