Hi,

I search a ansys tutorial to simulate the fragmentation of a solid body in interaction with explisive (ex pipe bomb, hand grenade...). If someone can help me! I use ansys v11. 

Thanks

I design, I love.
We focus on structure design. with perfect plastic, sheetmetal, diecast part part design experience.
We can do tolerance anlaysis for complex assemblies base on 6 sigmas.
We do Moldflow analysis for injection plastic part.

Hi Guys,

I have the shear relaxation modulus given as: G(t)=Go*EXP(-t/tau). In ABAQUS, the normalized shear modulus for one term in Prony series is given as: g(t)=Go(1-g1(1-EXP(-t/tau)). The parameters that must be entered in ABAQUS are g1 and tau. For Maxwell (in our case) G(t=infinity)=0.

Consequently, g1=1-G(t=infinity)/Go=1. ABAQUS requires that g1 must be less than 1. Has anyone encountered this problem?

thanks

Ah

I want to know what are the advantages and disadvantages of explicit and implicit time integration schemes? Can any one suggest me any book which is also available to free download.

Thanks

I will be highly grateful if u will say me how to link subroutines with abaqus....... intel fortran compiler is there.......... how to proceed now????????

Hi all ,

We were doing compression testing of alumina using Instron compression testor. plates used to compress the specimen is made up of Steel. When we applying load in elastic region we are not able to see right deflection because of compliance. Deflection of alumina is not clear as we are getting lots of compliance error. Has anyone faced similar problems. Is changing the steel plate and using any hard material in place of steel is the solution.

 Thanks

These two values are equivalent for bimaterial ?
