Hi, it would be greatly appreciated if anyone could tell me the methods to measure the elastic constants of an orthotropic composite (3D). Can we measure one single modulus by one specific stress state? What is the efficient way to do the test? Any information related to this test is appreciated.

Thanks and regards

Hi all,

I need to model a reinforced concrete slab in Abaqus, but actually I don't know how to build the reinforcement and how to assemble that by concrete slab. I appreciate it if anybody can send me an input file in this topic.

Thank you in advance,

Armin

Hi,

I am modeling a simply supported beam in ansys using a plane 183 element. In this case (A two dimensional beam model) how should I give the B.C.s? Should I apply B.C.s to

1)  the mid node on the edge of beam? or

2) to the entire edge? or

3)  just to the bottom node?

according to me the first choise seems OK. But the results are not satisfactotry. plz help.

Several month ago I login a account ,then writen my fist blog.But I can not think back my login email,so I have to login with a new email. In the last months ,Most of time was spend in program.My Boss except me to get repetition of Werner's work --computer simulation of dunes. Now I get work finished. It's amazing and excited.

This question seems easy but in fact it is NOT. i do not know how to mesh a ball with ONLY brick elements (no tetrahedron) using ANSYS. Please kindly send me an input file contains the meshing to a.abeed [at] tu-bs.de

i am a student. I would like to simulate impact of an elastic solid ball with rigid flat surface, I do not know how to create the best mesh for the ball so i obtain good results with ansys LS Dyna (drop test modue). of course there are some advice in DTM like avoiding tetrahedron or sharp edges, ... etc. please help me i think a ball meshed with brick element produce better results but, how can one mesh the ball entirely with only  bricks (no tetrahedron)

I need some assistance on how to model precast slabs and how to specify the properties of the connecting tie bar for the precast slabs using GSA Oasys.

 Help!
