I implement a program for fatigue crack growth in the XFEM.

But I have great difficulties to find material parameters used for PARIS- or  FORMAN/METTU-equation.

Can anyone point me where this parameters could be released, for example for epoxy, polyurethane, 18CrNiMo7-6 and Aluminium.

I would very appriciate your response.

RPIM

Submitted by 83684024 on

My research field is Numerical methods in fluid dynamic. The method that we use named CDLS mesh-less method. It is based on MLS shape function and Least square equation discretization.

We decide to change our shape function from MLS to RPIM. We predict if this shape function couple with our method, we will reach better results in fluid dynamic problems. But we don't have any experience in using this kind of shape functions.

Now I am looking for a person who has experience in working with RPIM shape function for cooperation.

Alternate expressions for the near-tip in-plane mixed-mode K-field stresses and displacements

Submitted by Dhirendra Kubair on

Alternate expressions for the angular variation of the K-field stresses and displacements around a sharp-crack embedded in an elastic medium subjected to an in-plane mixed-mode (mode-1 and -2) loading are presented. The expressions are derived in terms of the mode-mixity angle instead of superposing the pure-mode fields. The alternate expressions are derived using complex potentials and the Kolosov-Muskhelishvili method. The mixed-mode stress and displacement fields are presented in the crack-tip Cartesian and polar coordinates. We have obtained the crack growth angle in terms of the mixity-angle assuming the maximum hoop- and principal-stress criterions.

 

Thermal buckling analysis of a radially graded annular FG plate with temperature dependent properties

Submitted by omidomid on

Dear all

I'm working on the thermal buckling analysis of a radially graded annular FG plates with temperature dependent properties.

The results show that the temperature dependent thermal buckling loads are greater than those of the temperature independent, but I have expected for vice vesa results!

Can anyone explain it ?
