Ice or hail impact is an important design consideration in the aviation, energy, and astronautics industries.  Physical testing of impact scenarios can be expensive and impractical.  Numerical simulations provide cost effective and convenient tools for including hail impact scenarios in the design process.

Numerically simulating high speed ice or hail impact is challenging because of the extreme deformation, fragmentation, contact, and material model complexity.

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?

Dear all,

Does anybody how we can put a loop (for example while loop) inside a .psf (parametric study) file in abaqus?

For example a loop on all the increments we want to get a field variable output. Take a look at the following code:

Hi everyone,

 some one please help me! I need some standards names and title for a course project.

I am searching for standards for testing pressure drop in pipes, valves, sight glasses and other hydrulic components. also i need standards for testing pumps too(specially diapheragm pumps) . i used google, but i didnt find anything useful, please help me. 

Hi Everyone,
