Dear Friends,

I've simulated impact in ABAQUS. Internal and kinetic energy diagrams of process is very close to experimental data. But reaction forces are lower than experimental measurements and have too much fluctuation. Also Force-Displacement diagrams aren't acceptable. In reality, reaction force reach the maximum when displacement is maximum and impactor is beginning to move backward. But result of simulation shows maximum force during backward movement.

Sincerely yours

Hi all,

please give me an idea(script) to create a "DROPDOWN MENU" dialog box to extract User input in abaqus. By using getInput, I can ask for the same but I want to do it using dropdown dialog box.

 thanks in advance 

Hi,

  I'm Praveen doing my Master of Technology Project. I wanted to know how to model delaminated composites in ANSYS. Whether to use Teflon layer as delamination between the plies or creating air gap between the plies? And also wanted to know how to use cohesive zone elements or interface elements to create delamination. Can anyone help me? I ve attached images for references.

Polarization distributions around an open crack with different electrical boundary conditions in a single crystal ferroelectric are investigated by using a phase field model. The surface effect of polarization is taken into account in the phase field model, which has not been included in previous ferroelectric crack models. The simulation results show that the impermeable crack and the crack filled with air have a significant influence on the polarization distribution, while the permeable and the crack filled with water have little influence.

i am working on ABAQUS, trying to carry out pushover analysis, modeled dam body as well as foundation, can anybody explain me how to carry out pushover analysis of dam ,as well as which interaction is suitable in between dam and foundation interface.

thank you in advance.
