University of Colorado, Boulder



The research objective is to establish an ultrastructurally-based computational finite element model of the ocular lens subjected to dynamic loading to attempt to better understand the mechanisms of traumatic cataract formation and how it may be treated clinically.



Johanson Cook parameters

Submitted by monzer on

Hi, Every one i am student doing my masters and i have got the
experimental result from tensile test for different temperature stress vs strain and orthogonal cut .
but i am going to apply the Johnson cook material model. please can any
one give me how to find A,B,C,N and M please i have read it found from
the experimental data i have got but i didn't know how to find please

Submitted by Andrew Bunger on

CSIRO division of Earth Science and Resource Engineering is seeking a Senior Research Scientist in hydraulic fracturing/geomechanics. The position is located in Melbourne, Australia and the successful candidate will play a leading role in a world class hydraulic fracturing laboratory facility and in a hydraulic fracturing research team that integrates modelling with experimentation at laboratory and field scales.

Tensile testing curve and fracture toughness relation

Submitted by jjamali on

Hello everyone,

I am studying fracture of polymer composites.

I had a question I want to relate fracture toughness of composite to the composite stress-strain curve found from simple tensin test(on samples with no notch or pre-existing crack), can anyone give me a hint , how to do it?

An observation on the experimental measurement of dislocation density

(to appear in Journal of Elasticity)

The common practice of ignoring the elastic strain gradient in measurements of geometrically necessary dislocation (GND) density is critically examined. It is concluded that the practice may result in substantial errors. Our analysis points to the importance of spatial variations of the elastic strain field in relation to its magnitude in inferring estimates of dislocation density from measurements.
