Introduction to Finite Element Method
In the previous chapters, we developed tools for developing an understanding of heat transfer and shock and vibration issues. While these tools may suffice for solving design issues, they are not appropriate tools for conducting an in-depth analysis. For realistic problems of today, a numerical method-and mainly finite element method-is utilized. Nowadays, it is possible to use CAD software to “design” a system and then by the click of a button, solve for stresses and strains in various components without the slightest notion of any degree of accuracy.
