What is Explicit Dynamics in Ansys?

Published on July 9th, 2019 | by özgün

“Implicit” and “Explicit” refer to two types of time integration methods used to perform dynamic simulations. Explicit time integration is more accurate and efficient for simulations involving – Shock wave propagation – Large deformations and strains... Read More

How to Model Composite Structures

Published on February 27th, 2019 | by özgün

Composite structures have excellent strength to weight ratios and are used in many applications, including most of the airframe in modern aircraft as shown in Figure 1 (above). However, there are significant and obvious complicating features... Read More

Difference Between Static and Transient Analysis?

Published on January 16th, 2019 | by özgün

Most of the engineering problems are considered as dynamic although we mainly focused on solving static problems analytically in undergraduate educations. However, the term of dynamic might be confusing sometimes for those who are interested in... Read More

What is “Large Deflection” in Ansys ?

Published on September 19th, 2018 | by özgün

When performing structural finite element analysis (FEA), there are three types of nonlinearities that the analyst needs to consider including in their simulation. Material nonlinearities are needed to predict plastic strains in metallic parts, cracking or... Read More
