The salary is dependent on the location. For high cost of living, such as CA, 56K is low. But, at Texas, this amount is good.

What is the limit load analysis? Anyone can tell me, Thanks.

HI xerf, If you mean the material is purely elastic, no plasticity, EE33 should be zero?

rb1957, What is NASTRAN's GridPointForce balance? Thanks.

thanks again. My material is a linear one with stainless steel. It is not a contact roblem. I should be able to check the reaction force in ABAQUS at the displacement that I applied. prost, What do you mean by 100th the force? I applied the force in single step. It becomes unstable in the...

thanks for all reply. My problem becomes unstable because of too much force applied. I found that when I try to apply the displacement, instead of force/pressure and keep everything the same (mesh). It can converge. That's why I want displacement-controlled. For prost, my material behavior is...

If we use the shell elements, we should model the geometry (CAD) with mid-surface, but the inner or outer surface, then defining the thickness.

In my model, when I apply the force/pressure, model becomes unstable. I know applied displacement controlled can solve this problem. However, how do I know the value of displacement should I apply. Can I check the reaction force to ensure the displacement that I apply being the same the...

how can we model the weld with shell elements. The solid weld is not small in thickness of one direction compared with others.

Only one direction of reaction force is the same when you compare three cases. However, you will find the difference in other two directions. So, they are not the same reaction forces, but the difference is not much. If I were you, I prefer to apply the pressure in loading.

We usually outsource to the local consulting companies. Be careful of some oversea companies. Somehow, we told them what we need and the requirements. But the outcome is bad and cannot pass the standard as we need. Then, we need to find our employee to re-engineer their products and designs. It...

You need to check the reaction forces in all directions and you will see the difference.

I also consider to take the MBA. I am in mid 30. Some told me full-time is better than the part time. But, how come I can support without pay for two years and at the same time, pay school fee of at least 25,000 for one year. When employer see your resume, full-time is really important?

To know it is correct or wrong? Apply the loading in three cases, applying pressure, distributed or kinetic coupling loading.

A distributed coupling does not eliminate degrees of freedom at the coupling nodes. It distributes loads such that the resultant forces at the coupling nodes is equal to the forces at the reference node.
