Hello,

I would like to combine Extended Finite Element Method (XFEM) with cohesive behavior in Abaqus to model bulk damage as well as interlaminar damage in a material.

Section 10.6.1 of the Abaqus 6.9 Analysis Users Manual says that XFEM "can be simultaneously used with the surface-based cohesive behavior approach or the Virtual Crack Closure Technique, which are best suited for modeling interfacial delamination."

Does anyone know if XFEM can be combined with element-based cohesive behavior?

Thank you,

Meghan

Hi!!!
I am doing the modal analysis of a tapered cantilever beam with an lumped mass at the free end
I meshed with beam 188 and difine the crossection as rectangular at the both ends by SECTYPE,SECDATA command.
But how to connect the mass element at the free end?
I hv also gone through the VM34 example given in ANSYS help.
Please suggest.

I am looking for postdoctoral position in the field of mechanical and material engineering. I am currently a doctoral candidate at Louisiana State University, and expect to complete my PhD degree requirements by Jan. 2011.

 

Dear all,

I'm writting an usermat into a vectorized subroutine in LS DYNA. The implementation is a non-local model based on an avarage of the strains.

For the implementation I need to know the strains for all the elements at each iteration to compute the non-local strains of all the elements.

Hi, i need help modeling sandwich structure in ANSYS 12.1, i have found some materials online on how to do it? I have tried the basic steps. got some results, but now how do i validate that.   I have experimental data for three point bending. But i want to make sure that what i am doing in ANSYS APDL is darn right. 

inputs are,

3 layers 45/0/45

thickness 0.1/0.365748/0.1   (inch)

material i am using right now are carbon fiber and foam DH100

properties of each layer have been assumed to be isotropic

 carbon fiber weave

My name is Georges Ayoub; I am seekinging a postdoctoral research position in mechanical and material engineering. I defended my PHD at the beginning of this academic year (2010/2011) and the examining committee gave me the title of doctor in mechanical engineering with a very honourable mention and with the examining committee praise (they judged my work as an excellent one). I am very motivated to start a Postdoctoral position in January, in the USA.

  Hellow!Everyone here.In my study,I need the crack growth constants of 2524-T3 alloy,such as C,n,Kic.Who can help me?

Respected Sir

what is the difference between the B magnetic field & H magnetic field? 

Hi, everyone ,,,I am a new user using ansys, i am working with pipe model. I build my pipe with solid 42 and solid 45 and meshing it. However,after running it,  I cant see the result summary at POST1 even in the output window the result showed. Any one have a problem like this? if yes..how to solve it ,,,thanks
