Johanson Cook parameters
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
An observation on the experimental measurement of dislocation density
Amit Acharya and Robin J. Knops
(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.
crack propagation using Cohesive Zone approach
Hi
I have problem in Abaqus for crack propagation using cohesive zone approach in 3d for my research work
Is it possible to define a dimensionless number being capable of characterizing the two effects with totally opposite direction?
1. assuming to exist a PDE describing an equilibrium along one direction (e.g., postive direction along X coordinate), A+B=0;
2. after normalization process to the above PDE, we got, A*+(C)B*=0;
3. (C)=B/A, is the dimensionless number, and obviously, (C) implicits that both two effects arising from A and B are the same in the direction, i.e., along the X positive coordanate;
