Boundary Conditions in Unit Cell with ABAQUS

Submitted by M.A. Rahman on

Hey,

I am trying to do simulation of one eighth of the unit cell with single void at the center in ABAQUS. I have problem with boundary conditions. I am using *Equation constraint in ABAQUS. But it is not working properly. I can not figure it out which one or two should be my control points or master nodes and what DOF should be used. Can anyone give me suggesations regarding this problem. Thanks in advance.

 

Local water slamming impact on sandwich composite hulls

Submitted by kaushik das on

Recently we analyzed water-slamming impacts on sandwich composite hulls. Water slamming impact problems are very interesting problems involving fluid-structure interactions.  A link to our paper and the abstract are given below. I hope that you will find the paper interesting. Please feel free to write your comments below.

ANSYS MPC-184

Submitted by Pooyan on

Hello

I want to model a 2-D frame with BEAM3 element as beam and columns. As I know the
connection between the beam and the column created by ANSYS is rigid. My aim is
to create an hinge connection between the beam and the column.

My problem is modeling this hinge connection, I used MPC184-revolunt joint but I
don't know how to model hinge by MPC184-revolunt element correctly.

Can someone help me to model it?

Harmonic Analysis using LMM

Submitted by vj_sen on

I am working in ANSYS multiphysics for vibration analysis of electronic equipments. To find out absolute displacement on cards in Harmonic Analysis by using Large Mass Method, I need to give 1g acceleration on Large Mass. I am applying (Large Mass*9.81*1) force on Large Mass so as to simulate 1g accleration but response at same LM location after analysis is coming 2.5g. Can anybody suggest any alternate method of doing it?
