ABAQUS

Hi colleague

can you help me to define a cyclic load of 1 kN (120 cycle per min ) in Abaqus?

does it diifrent to use static or dynamic analysis?

Thanks. 

Hi

is there a way to get the characteristic length of one element? I wanna calculate xult (when the element is cracked, fracutred..). 

 I use the concrete damage plasticity model and after reaching the tensile strength i assume a linear softening with fracture energy.

Input are:

   Young´s modulus

   max. tensile strength

   fracture energy

Outpu:

   when do i reach xult or what is the plastic strain equivalent

Hi, everyone:

    I'm recently very interested in computational nolinearity. Would you like recommend some monographs on the computation nonlinearity so that i can have a better understanding of the mechanism of ABAQUS.

    Thanks

 Dear all:

    I recently find an example in ABAQUS documentation cannont convergence.

    The parametres related with the iteration of the Risk method is 

Hi colleague

 does anybody know, what is this strange error :   Error in connection to analysis

i am trying to model fracture mechanics on piezoelecteric material, when i select the piezoelectric as a familiy in mesh part, then when runing the model, i recieve this error. if anybody knows how to fix it please help me.thanks 

Dear valuable members,

Thanks for the kind help in advance.

I would submit a well known error that I got in my run of
the UEL subroutine which has additional dof. the error is:

Abaqus Error: The executable
/abaqus/6.11-2/exec/standard.exe

Hi,



I am using the VCCT method to model crack propagation and I am finding the value of G/Gc is too large for any sensible time step (1e-25).



I am attempting to incorporate a time incrementation scheme into my UMAT which monitors EFENRRTR and modifies the time step (or PNEWDT) according to it's value.
