Overview of Explicit and Implicit Dynamic FEM Analysis in PAK Software

Abstract

Dynamic analysis of engineering structures is essential in the design process, providing insights into their behavior under various loading conditions. This paper focuses on the comparative study of implicit and explicit dynamic analysis methods using the PAK software and FEMAP with the Nastran software. Both methods have distinct advantages and disadvantages, which are examined in detail through the simulations of simple examples. The influence of the solution methods on the results is critically analyzed, offering valuable insights into selecting the appropriate dynamic analysis technique. The results from PAK software are validated through comparison with FEMAP with Nastran software, highlighting the accuracy of both software in dynamic analysis.
