Methods of Solving Problems in Structural Mechanics

In this learning track, the methods of solving structural mechanics problems are explored. The concepts that are necessary to solve more advanced problems are introduced. The prerequisite courses are “Understanding the Physics of Structural Mechanics” and “Capturing Complex Response.” In those learning tracks, we built a strong foundation of structural mechanics basics and then explored more complex behavior and response. Now, we will build upon this foundation and focus on the methods of solving problems. Completion of this learning track will provide you with a more advanced understanding of solving simulation problems that are increasingly more complex.

Mode Superposition Method

Do you want to capture the frequency response of a system in a limited loading range of frequency but do not want to solve a large, time-consuming dynamic analysis? Mode superposition (MSUP) is computationally less time consuming and finds the response for a given loading by a...Read more

Harmonic Analysis of Structures

In most engineering problems, we want to predict the response of structures to an external loading/excitation, which is the real-life case. There are many examples where we may see resonance or even failure due to external loading acting at a certain frequency. We first...Read more

Time Integration

Time is continuous. Seconds, milliseconds or even microseconds are not the smallest unit of time, because it can be divided into infinite time points. Therefore, in simulation, it’s impossible for us to find a structure’s behavior at every single time point.What we can do is to solve ...Read more

Computational Considerations

Solving a problem and computing to achieve a final product requires many iterations. The more complex the problem, the more iterations are required. In this course, we will focus on how Ansys software solves a simulation problem and the computational re...Read more

Hyperelasticity

While most conventional metals undergo plastic deformation at very small to moderate strains, there is a class of non-metallic materials that can exhibit elastic behavior at strains as high as 30% or more, while developing very little or no detectable plastic strain. In this Ansys Innov...Read more

Structural Instabilities

Structural instability is a phenomenon where a structure deforms a lot while the external force increases by a small amount. In this Ansys Innovation Course on “Structural Instabilities”, we will present a focused discussion on two categories of structural instability: dynamic ...Read more
