Dear All,
I am very new to Abaqus. I only know little about pre-processing and post-processing approach.
I often heard about the using subroutine in Abaqus. Why should we use subroutines in Abaqus ?
Thanks
Hello there
I am working on gradient plasticity implementation by using UMAT in Abaqus software.
I need to access the value of total strain incriment for all integration points after the UMAT has been called for the first integration point.
As I know, the value of strian incriment for one specific integration point will be passed to UMAT when that point called through UMAT,
but I just wonder is there any way to get these values at the starting point of each time incriment and do not wait for Abaqus to call all integration points.
In this paper we make a connection between covariant elasticity based on covariance of energy balance and Lagrangian field theory of elasticity with two background metrics. We use Kuchar's idea of reparametrization of field theories and make elasticity generally covariant by introducing a "covariance field", which is a time-independent spatial diffeomorphism. We define a modified action for parameterized elasticity and show that the Doyle-Ericksen formula and spatial homogeneity of the Lagrangian density are among its Euler-Lagrange (EL) equations.

Dear All,
I am going to draw a 3-D model to be run in Abaqus. I would like to know how I can do that.
I find it is a little bit cumplicated to design the 3-D structure with certain curvatures in CAE.
Could anyone tell any assisting softwares or approaches of designing the 3-D geometry in a simpler way for finite element analysis?
Many thanks,
Jay
Hi to all
I am working on modeling of cantilver beam under cyclic loading by Abaqus-Explicit. hysterisis curve doest seem reasonable.
I have tried several type of hardening law and material, but it didnt change the results.
I will be thankfull for your guidence.
