A few guidelines show how to correctly use FEA stresses to find reasonable margins of safety. Although finite-element analysis has become an indispensable part of engineering, a few users knock it ...

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 ...

Sometimes, it’s easy for a computer to predict the future. Simple phenomena, such as how sap flows down a tree trunk, are straightforward and can be captured in a few lines of code using what ...

A non-linear example vehicle model including four degrees of freedom (yaw, sideslip, roll and steering), non-linear kinematics and the Magic Formula tyre model has been developed. With the assumption ...
