Dear All,I am studying cyclic loading, Plasticity and metal ratchetting. All the publication related to these topics mention about backstress. Please somebody explain me what is the backstress. Could you please suggest me a reference to learn fundamentals?bandula
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.
The Laboratory for Advanced Materials at Pittsburgh has openings for
one graduate student and one postdoctoral research fellow for 2011.
Interested applicants should send their materials to Professor Paul W.

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?
