I am trying to do deep drawing in ABAQUS. While to do this, I'm getting help
to ABAQUS examples which is name Deep Drawing a Square Box. In my model
looks everything is ok. But my punch reaction force is very low. In addition
I did this model experiment in our laboratory. For example my model max
punch force 4000 N but in experiment real punch force for same material
nearly 12000 N. My model link is below:

Has anybody written the algorithm?

Pressure vessel deflection
Hi,
I have observed in many cases that horizontal pressure vessel with saddle support due to the internal pressure gets circumferentially compressed (vertical deflection).
Can anyone expalin why it behaves so.
Attached is the pic showing the pressure vessel.

Piezoelectricity above the Curie temperature? Combining flexoelectricity and functional grading to enable high-temperature elect
Most technologically relevant ferroelectrics typically lose piezoelectricity above the Curie temperature. This limits their use to relatively low temperatures. In this Letter, exploiting a combination of flexoelectricity and simple functional grading, we propose a strategy for high-temperature electromechanical coupling in a standard thin film configuration.
Shear lock free Timoshenko finite element for thin to thick beam
