crash test using abaqus
halo, i'm using abaqus for the crash test analysis of car body ,the problem is the contact between the bodies any help or examples and thanks in advance.
abaqus question
I'M USING ABAQUS IN MODELING A BEAM UNDER flexural, "BENDING". my problem is the concrete material model with tension stiffening. my problem is occured repeatedly for all element types.
Although, i imported the input files obtained from the ABAQUS ducomentaion for support; the same error obtained.. the programe message is
The plasticity/creep/connector friction algorithm did not converge at 10 points
Spectrum Analysis in ANSYS
Hi all,
After untyring efforts i was able to do modal analysis and i am happy that alot people are helping at this forum. Now the problem i am facing is that after modal analysis i am carrying our spectrum analysis. I have selected PSD as my spectrum analysis. I have all the statistical data of PSD table i.e Frequency Vs PSD. After entring the PSD table i have to apply the boundary conditions. I use following path to for Boundary Conditions.

MRS symposium LL "Architectured Multifunctional Materials", Call for Abstracts
Deadline for Abstract submission: November 3. See www.mrs.org/spring2009. A symposium entitled "Architectured Multifunctional Materials" will be organized at the MRS-spring meeting in San Francisco next year (April 13-17, 2009). For details see below and attached file.
Pressure on circular area of a semi-infinite plane: typos in textbooks "contact mechanics" "surface mechanics" "elasticity"
This is supposed to be a very classic analytical solution in applied elasticity. Forgive me if this is a repost or some correction has been made before. I had a hard time with it.
Problem statement: uniform pressure is applied on cirular area (radius=r) on top of a semi-infinite plane. Find the vertical deflection.
We got discrepancy between FEA solution and analytical solution which I found from different textbooks (famous and non-famous): Deflection within the circle is good, however, no good outside the circle.
ANSYS: melting using element death--how to transfer convection BC from deactivated elements?
I am modelling melting by element death. I have a cold (melting) rectangle with a hot fluid convecting at the exterior. I am using a do loop so that time increases at each loop. I define a "melting" temperature, so that elements are killed off when they achieve a specified temperature.
Interpretting results in ANSYS
I have done modal analysis and when ANSYS asked to input the start and end frequency i typed 150 as my starting frequency and 2000 as my ending frequency. No of modes to extract 10 and no of modes to expand 10. Due to no of modes ANSYS has only displyed 10 results. When i entered in postproc and results summary only 10 results were displayed and starting frequency was 150.01 to 150. 39. Now if i want to see all the frequencies how is this possible???Should i maximise the no of modes or is their any other option to view the results???
creep
hi every body
can you help me about creep constant for cr ni steel
or about perform a proper creep with ansys
thanks alot
Modelling crack in Ansys with interface elements
Hi Every body
I am Dhaneshwar Mishra, a PhD student working in the area of fracture mechanics, basically fracture failure of interfaces of bimaterial, composite layers etc. I am regular reader of IMechanica and got lots of insights by reading different postings on it. I am trying to model the interface in ANSYS 10.0 with their Interface element INTER204. While searching this element in Ansys element library, i could not find it. Will some body guide me to model interface of composite layers using the concept of cohesive zone modelling?
Thank you
