Shape memory alloys (SMAs) are intermetallic alloys displaying recoverable strains that can be an order of magnitude greater than in traditional alloys due to their capacity to undergo a thermal and/or stress-induced martensitic phase transformation. Since their discovery, the SMA industry has been dominated by products for biomedical applications with geometrically small feature sizes, especially endovascular stents.
Erdemir Laboratory at the Cleveland Clinic (http://www.lerner.ccf.org/bme/erdemir/lab/) has three positions for an upcoming project on the biomechanics of multi-layer tissue structures of musculoskeletal extremities with emphasis on computational modeling & simulation. The positions will initially be for a duration of one year with the possible extension to three years.
Modeling and Simulation Engineer – FEA

Job Description
Dear ALL,
Does anyone here has an experience carry out FE analysis for a part[bracket] which was deformed plastically during cyclic loading test.
I'm now working to resolve this issue when a bracket was fail to withstand the constant loading of 500N during cyclic test. It was reported fail at ~3800 cycles which was less than target.
Rgds.
Dear ALL,
Which reading material/source that describes the good understanding of stress triaxiality?
What is the role of stress triaxiality for FE analyst?
I have read a lot of papers/articles but still have confusing me on the fundamental of stress triaxiality.
ADINA R & D is seeking an Application Engineer with a strong background in solid mechanics and finite element analysis to help develop the ADINA market and support customers.
Hi
I'm facing problem while writing a script for a parametric study.
After changing the each parameter the model changes and and the loaction of the interested element changes based on those parameters.
Also the element number changes.
Is there any command in python script to choose the elements based on the location ?
Thank you in advance

I have a one dimensional bar with a triangular pulse given at one end for 2 microseconds. The boundary conditions are free-free.I am having two cases. One in which the deformation is local (Hooke's law) and other in which the deformation is dependent on a kernel of radius r (say 5* element length).I find that the wave speed is higher when the deformation is non-local as compared to local deformation case. Is this correct? Is there a way to verify the solution?
