Dear sir at present iam doing meshing in hypermesh i want to know that imeshed a component with tethedral elements iwant to know that whether i can apply the properties of solid 45 element to these tetrahedral elements

Dear friends,
I am trying to find thife transient dynamics response of clamped clamped laminated cylindrical shell subjected to Radial impulsive load. I am getting very irregular response using Newmark Integration scheme. But, using HHT-alpha method, high frequency noise from the response gets removed, but damping is intrdoced (Numerical Damping). Although i have not introduced and damping in my model. How to overcome this problem.
I need help in this regard.
Regards
Hi I need a help if anyone can solve my problem please help me out. I want to use the output file of the result as a input file in ABAQUS i.e, if a apply tensile load to a model it will elongate and I need the elongated model as a input file for carrying out the next step. If anyone can pl send me the .jnl file or .inp or .cae file. I am using ABAQUS/STANDARD VERSION 6.8
I’ll present this below without the answer, in case you want to enjoy a little brain teaser. It is a solid and experimental mechanics problem that, while not terribly practical, I found very interesting:
A part fractures cleanly in two by brittle fracture (no plasticity) under the action of residual and applied stresses. You only have the broken part in front of you, no prior information.
What were the original residual stresses on the fracture plane?
Dear all:
I want to simulate the inclusion-matrix debonding under tensile load with abaqus cohesive element.But when I added the cohesive element around the inclusion, the stress filed was totally changed. I think it is because the stiffness of the cohesive element (K/G1/G2)was not right. Do you know how to choose it so it will not affect the stress field of the oringinal structrure? or can you give me an example? Thanks very much.
I am simulating a cube of sides 10 units. I have applied the
load as pressure of 16 units at top. The cube is meshed by usign a
global seed size of 5. It means, there are 9 elements and 27 nodes
(using C3D8R). I have used the material property of steel for instance.
The base of the cube is fixed and the sides are allowed to move
vertically. Now i want to calculate the nodal force at the centre of
the cube i.e. at the centroid of the cube (not in the centre of any of
the exterior sides).
The element is added displacement load in one direction, at the steptime=0, the nodal displacement is zero, and so as the integrated points' strain and stress. However, the internal force NFORC is nonzero. When we calculate internal force by ourselves, it is obtained by the integral for BT*stress. But the stress is zero, how Abaqus calculates the nonzero initial internal force?
The details can be found in the attachment.
Hello,
I am having issues running an Eigen value simulation on a bridge model that I have developed. The model consists of a bridge super-structure supported by pinned connections on the ends of the bridge length and a roller support in the middle.
The model runs without errors when I do not request an Eigen value analysis, but aborts when I request an Eigen analysis. The message file sites the cause as a factorization error. Warnings also appear stating a zero pivot when releasing the 1st dof of the nodes associated with the roller connection.
