high strain rate

computational mechanics of materials

Impact analysis

There is still time to apply the 5-year post-doctoral position at the University of Southampton. We are looking for a talented young researcher to join a group working on the definition of the next generation of high strain rate tests based on ultra-high speed deformation imaging and inverse identification (PhotoDyn project). Please apply online before September 30th.

I test the proficiency of SPH method dealing with a benchmark numerical example solving Poisson's equation; SPH shows the good efficiency in modeling the contours, but the value of results change for a different nodal distributions (different

I wrote these notes as a background for teaching elasticity and plasticity. Even in this most basic formulation, the dilation of the fluid is viscoelastic.

Load Displacement curve for XFEM in ABAQUS

ABAQUS

fracture mechanics

Abaqus XFEM

ABAQUS XFEM crack propagation

I am using Maxps Damage criteria for an XFEM crack for a three point bending case. I am using displacement loading on the specimen and wish to plot reaction load v/s mouth opening displacement. I would like to know how to obtain the crack tip opening displacement in ABAQUS. All the journal papers I read show a slump in reaction force after the crack starts to propagate. I plot the results and contour plots show me clearly that the crack has started to propagate. Please help.

equivalent strain

Dear reaserchers

Here is my question in developing the eqivalent strain via in-plane stress problems. please let me find your answers.

I did an experimental test on a 6 mm thickness plate. Principal strains (ε₁,ε₂) was developed from recorded strains via Rosset strain gauges . To develop the equivalent strains I need ε_{1 ,}ε_{2 ,}ε₃ in the following eqation:

dε_e=(√2/3)(dε₁²+dε₂²+dε₃²)^1/2
