Hi,
I am working on a coupled fluid structure problem , precisley on the elasto-acoustic mode, of a system consist on a cube which define the fluid domain coupled with an elastic plate.
The boundry conditions is:
- all the face of the cube is regid only the face coupled with the plate
- the plate is simply supported at the interface
Tenure track positions at Halmstad University
Halmstad University (Sweden) is looking for young researchers to join our research groups in embedded and intelligent systems, specifically for intelligent vehicles in joint work with Volvo Technology in Gothenburg. Two positions are currently open: one with a focus on vehicle diagnostics, maintenance and uptime, and one with a focus on autonomous vehicles.
Remeshing when using Abaqus
Hi
I am modelling a contact problem using Abaqus and I am trying to use remeshing hoping to get more accurate results in critical locations. But I encounter following error:" the area of 7 elements is zero, small or negative". Despite of the definitions of the remeshing rules always the error message appears when size of elements is quite a small. My goal is to get minimum element size 1E-7m in critical location. The error message appears much before that goal. I am very grateful if someone could help.
Looking for a PhD student
A Ph.D. position has recently become available in my research group (www.eng.uwyo.edu/mechanical/research/frick/), to explore thermo-mechanical
behavior of shape memory polymers for biomedical applications. A
strong candidate with a M.S. or B.S. degree in Mechanical Engineering,
Materials Science, or a related discipline is required. A good
academic record, a clear interest in experimental sciences, and an
enthusiasm to conduct outstanding research are the only prerequisites.
poroelasticity
Does anyone have experience using poroelasticity model? I dont underestand the abaqus model -the logarithmic bulk modulus and.., where are these coming from?Is anyone knows a reference book to link those?
dynamic crack propagation
Hello everyone, I am useing the CZM method researching the dynamic crack propation problem in composites,so I must have the UEL OR VUEL of cohesive zone elements in ABAQUS or other FEM software,at this moment, i have a UEL of ABAQUS,so i have a question ,if i want to simulate the dynamic crack problem, can i use the UEL? Or must write my VUEL?
Everyone answer is welcome
If some people have the same researching plan ,we can communicate each other!
For metals, when will the elastic modulus be changed?
I have a question, for the same metal material, when will the elastic modulus will be changed? in another words, in what kind of processing or machine condition will the elastic modulus be changed? for example, to machine elements(gear, bearing ...), when the part surface is case hardened,will the elastic modulus be changed? if not, how can the difference of hardness between case hardened surface and without hardened substrate be reflected in FEM analysis? how can the case hardened surface parameters affect the contact stress when two part are brought to contact?
Structures in fire
Hi,
Are there researchers working on specific areas in offshore structures? Or is anyone covering the material behaviour of structures at elevated temperatures? I am indeed challenged to read about excitng contributions from different scholars expecially in structural mechanics. I realise I have just begun a race in research. You could help me gain the proper direction in research.
I shall be glad to get any response.
