Reliable FE simulations of human bones.

 

Patient-Specific FE-models constructed from CT-scans are

validated by experimental observations.  Fracture risk laws are sought (funded project).

The following pictures show a FE analysis of a femur and a typical experiement of a fresh frozen femur (from left: Nir, Zohar, Ilan, Romina, Natan).

Generalized fracture mechanics.

 

Numerical, analytical and experimental research on generalized failure

criterion in 3-D mechanical components (funded project ).

                  

Pictures show a 3P bending experiment and the FE of a V-notched specimen.

     

    

 
 

Simulation of a coupled thermo-finite deformation process (SPS) including uncertainy quantification.

Simulation of powder sintering under heat-pressure and electrical field. The aim is to construct a simulation capability and investigate how uncertainty in material properties propagate to the simulation results (funded project in collaboration with German and Israeli colleagues).

Generalized edge stress intensity functions (ESIFs) in three-dimensional domains.

The elastic solution in the vicinity of a realistic 3-dimensional edge (as a crack front) is derived and ESIFs are extracted from FE solution by a quasi-dual function method (funded project).

 

 

p-FE for bio-mechanics of arteries:

Incorporating hyperelastic constitutive models, active response, blood-wall interaction.

 

Incorporating hyperelastic constitutive models (passive and active response) of human arteries in the framework of p-FEMs.

Performing experiments on human arteries in active state.

The following pictures show our experimental equipment and a high-order FE analysis including active response.
