element subroutines

history dependent problems

Hi all,

my question is about the history data storage in FEAP.

I am writing element subroutine (elmt01) in FEAP 8.3 for a history dependent problem.

I have written the stiffness matrix subroutine (stiff01), but it needs the data from the previous solution steps (previous strains, stresses, plastic strains, dislocation densities .... nh1,nh2=30 per point).

j-integral

Hi,

I am trying to solve a 3PB specimen with a notch. I am doing the dynamic explicit analysis. I want to find the J-integral. Giving the J-integral as history output. Trying to run it gives following error.

Vibration of Circular Plates

Dear All,
These days I am do some research on vibration of circular plates (out-of-plane and in-plane). In the reference, the displacement in radial direction can be expressed with Bessel polynomial. I want to use the Rayleigh-Ritz method to solve these problems. The strain energy and kinetic energy can obtain with integral. If there is the bessel function, how to calculate the integral. Also I want to consider some spring in the boundary to change the boundary conditions.

ABAQUS CRACK PROPAGATION

how to do a crack propagation analysis?

can abaqus be used for doing crack propagation analysis for plates with multiple cracks?

Is Latent Heat for phase tranformation is mandatory for all kind of gases/liquid?

Submitted by sanjayiway on Thu, 02/16/2012 - 06:42

Like water, which keep change in phase from vapour, liquid, solid by adding required latent heat at constant temperature. Is this mandatory for all gaes like oxygen, nitrogen, any metal.
