Dear Sir/Madam,

My name is Muhammad Imran and I am working on experimental fatigue life calculation of aluminium-silicon alloy and validation of experimental results with abaqus fatigue results. The fatigue simulation is totally new topic for me and I don't have any idea how to apply fatigue loads in abaqus. 

During fatigue experiments, 100MPa (constant amplitude, sinusoidal) stress is applied at 20Hz frequency which led to specimen failure after 268220 cycles. I want to input these parameters in abaqus.

Hello ANSYS masters, I am student of M.Tech and I am currently doing my dissertation on Friction stir welding stimulation using ANSYS Mechnical APDL. The problem I face is in defining the time substep in the load step defined as follows

Dear friends

Hi. I'm working on multiscale modeling of soft tissues. In my research I faced with a problem about computing the jacobian matrix in ABAQUS UMAT. In my model the material properties are function of external parameter like ef (ef is kind of strain and obtained from loading conditions) and  relation between the "ef" and the strin in the model in unkown. Now, i want to calculate the jacubian matrix for this material, as you konw, the jacobian is defined as delta_sigma/delta_epsilon.

I have two question;

Dear all,

           I am trying to study the fracture at bonded interfaces using cohesive zone model in Abaqus. I am going through the abaqus manual but it was not clear how to insert the chosive elements in the model. How to model these chosive elements. Can anyone help in modelling the chosive elements.
