Here's when to use linear-static FEA and when to use a nonlinear program. Most engineering problems contain nonlinear effects. Take a paper clip, for example. Push on one end hard enough and the clip ...
• Most problems are nonlinear from the get-go. • Simplified load-deflection cases can help explain nonlinear (structural) FEA. Which designers need nonlinear FEA and why? Actually, projects ranging ...
