Nonlinear Material Model using ANSYS

Submitted by riteshparikh on Wed, 11/16/2011 - 11:28

I am performing the static analysis on hydraulics component where I am using the nonlinear material properties with multilinear kinematic material model having yield ~150 ksi and ultimate strength ~210 ksi. However I am getting first principal stress as 280 ksi and von Mises(equivalent) stress ~ 240 ksi.

I checked for the directional stresses where I find the stress in axial direction as ~279 ksi.

Whether it is possible to have the stresses above the given material limit (in this case true ultimate strength is 210 ksi).

Fracture toughness analysis of composites

Hello,

I am doing my thesis on fracture toughness analysis ofcomposite material. Basically my work is to estimate stress intensity factorwhen reinforcement particle is very near to crack tip. I am using ANSYS for modeling and meshing.

I need help in selection of element type for crack tip,matrix material and reinforcement particle. And how to calculate KIc forcomposite material???

Thank you.

ansys

can anybody tell me how to model composite plate in ansys?? And how to solve it? Specify me what type of element should be used.

Is it a bug? can't manage displacement amplitude when applying it via function

acoustic waves

harmonic displacement

Hello,
everyone!

I’m trying
to simulate different types of acoustic waves in linear anisotropic crystal in
order to measure their propagation speed (phase speed), and compare it with
experimental data.

Empirical observations of temperature

I have divided the old notes on temperature into three parts:

Principle of the conservation of energy
Empirical observations of temperature (this part)
Energy and fundamental postulate

Our feeling of hotness comes from everyday experiences. These experiences indicate that many levels of hotness exist, and that all levels of hotness can be mapped to a real variable.
