Hi, I am doing project on mixed mode crack growth of semi elliptical crack in gas turbine components under cyclic loading. Ansys has capability for finding J,K using CINT command. But, In mixed mode crack growth, i dont know how to deal with nodes and how to create random crack with new node coordinates obtained from previous steps. If you have any ansys code related to creating crack and finding fracture parameters like K, J (mode 1 or mixed mode), Can you please give me the code.

Thanks

(I cant use any other software, only Ansys)

Hi, I am using Ansys Apdl for 3d fatigue crack growth. I need any one code to understand how it can be automized (recreating crack with node shift and remeshing).

Thank you

Creasing and wrinkling instability are two distinct surface instability modes characterized by localized singular folds and continuous smooth undulations, respectively. In this article, we show that the surface of a soft elastomer may develop wrinkles or creases under compression and the action of gravitational force, depending on the magnitude of gravitational force.

Hi,

I am using HETVAL in abaqus to generate the heat. I am testing my subroutine and I set the flux(1) to a constant, like 5000000, but the output 'HFL', which I think should equal to the flux(1), turns out to be a very small number, and also it is a linearly increasing curve w/ time. Thus, the temperature is nearly not increasing.

I am also using the same problem using DFLUX.

Can anyone help me out?

Thanks!

In the section “Composites” of the ISD, a postdoc position in the area of damage modeling of composite and layered structures is available from now.

A while ago, I shared news about the recent publication of our review paper titled: "Practical Application of the Stochastic Finite Element Method".  The first author David Arregui-Mena, a PhD student at the University of Manchester, created a YouTube movie which summarises the content of the paper.

For those interested, its worth a watch!
