Hi,
I hape a relatively simple question. I am trying to set a maxmimum time step for a job by the lines:
*Static, allsdtol=0, continue=NO
0.05, 1., 1e-25, 0.05
so I believe the maximum time step should be 0.05 giving me a minimum of 20 increments in the step in total. However the STA file below shows that the job starts at 0.05 and the appears to ignore the maximum time step command. Can anyone tell me why this occurs?
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

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.
Hi
I have problem in Abaqus for crack propagation using cohesive zone approach in 3d for my research work
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;
