Postdoctoral Position in Biomedical Engineering

Submitted by rugonyis on

A postdoctoral research position is available in Dr. Rugonyi’s lab in the Biomedical Engineering (BME) Division of the Oregon Health & Science University (OHSU) in Portland, OR.  We are looking for a self-motivated researcher to work full time on projects related to blood flow dynamics and biotransport.  The selected candidate will have many opportunities to collaborate with the researchers in our team as well as across the university and to generate new approaches to study blood flow, biotransport and/or responses of the underlying tissue.

Hi all

            I want to know about Geometric Stiffness Matrix. When we calculate the stiffness of a body when the body is deformed then the stiffness called geometric stiffness. I have refered few books but I could not get the satisfactory details. I want to find the geometric stiffness of a fluid. I dont have any idea about geometric stiffnes. Any reference for this? Any article which explains this?

Hi All,

I am into machining simulation of 50CrMo4 Steel in DEFORM 3D and I need the flow stress curve data for various temperature and various strain rates. I have searched in as many journals as possible, but in vain. It would be of immense help if some one could share the material model data with me.

Thanking you in advance

With Best Regards

The J integral

Submitted by Zhigang Suo on

For a crack in an elastic body subject to a load, the elastic energy stored in the body is a function of two independent variables: the displacement of the load, and the area of the crack. The energy release rate is defined by the partial derivative of the elastic energy of the body with respect to the area of the crack.

This is a preprint that is going to appear on Applied Physics Letters. It is somewhat related to a paper by Kaushik Dayal on complex crystalline structure via phase field simulation that was posted here.

Stiffness with loss of material

Submitted by vishnusworld on

Dear All

I am modeling a workpiece supported in fixtures and being machined. I use the FEM ( Ansys) to simulate this set up. I need to know at the stiffness of wp at the wp-fixture contact point  . Stiffness is found by applying unit force at one contact point while fixing all others.. Inverse of displaceemnt gives the stiffness in that direction. I have two questions reg this.
