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?
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.

tsai wu failure criteria in ANSYS
dear friends, i want to know how to get the tsai -wu failure criteria for orthotropic material in ANSYS.after modelling and giving the material properties ,should i give anything special to activate this option ,or will i get automatically this criteria for all the elements from the output file itself.
please help me as my research work couldnt able to proceed.
Modelling isotropic hardening
Forums

Hi
I am having difficulty with modelling isotropic hardening for sheet metal material in a simple spreadsheet or MathCAD program.
I can model the initial yield condition using an appropriate (plane stress) yield criterion. I have also fitted a hardening law to the experimental data for uniaxial tension. I am having difficulty with the effective stress-strain relations and how this relates back to yield surface expansion.
Has anyone modelled experimental data in this way?
Is there anybody who are still studying elastic vibration theory?
I'm a graduate student studying the coupled elastic vibration prolbem of structures and soils. However, I'm not very interested in that, as I think the practical coupled structure and soil vibration problem is totally inelastic, and I don't think it is of great importance to study the elastic case.
Is there anybody studying the vibration problem here and can you tell me what's the importance of studying the elastic vibration problem? Are you interested in inelastic vibration prolbem?
