The UCD School of Mechanical and Materials Engineering seeks to appoint an outstanding academic with a suitably strong record in Materials Processing. The post holder will be expected to contribute to the teaching of existing modules (i.e., Computational Continuum Mechanics II, Materials Science & Engineering I, Mechanical Engineering Design I) and to be responsible for delivering the core mechanical engineering module, Manufacturing Engineering I, as well as to develop additional under-graduate and masters level modules.

Hello,

I want to download Abaqus on my pc but I fail .

Someone can help me to download this tools .

Thank you

Hello everyone.

I am trying to do something with the deformation gradient in UMAT. I used F=DFGRD0 as the gradient. but i found that it always comes to be a identity tensor not only for the case of a 3d isotropic elastic material but also for the ramberg osgood model. it was very surprising for me so i also tried to print DFGRD1 it was also identity tensor.

I have used a C3D8 single element and was doing the uniaxial test. Please help me out with this.

In Classical Continuum Mechanics, the entropy(s) and temperature(T) are considered to be dual in the second thermodynamics principle,

by define a relation between internal energy(e) and Helmhotz free energy(ψ): ψ = e - s * T .  As you can find it in many CM books, such as [2008][J.N.Reddy]Introduction to Continuum Mechanics.

Here is my questions:

1. Is the transformation between internal energy and Helmhotz free energy a Legendre Transform?

I am trying to model a simple compression test (50% reduction in height) using Abaqus.

So for this, I have a lower die, Specimen and an upper die.

The dies are modeled as deformable, and I've also added reference points to both the dies so that I can add a rigid body constraint to both of the dies.

For the boundary condition, I've fixed the top die and for the lower die I've applied a velocity of 10. 

I'm unable to get a 50% reduction in height. Can someone please help me with this?

I am using cohesive elements coupled with USDFLD subroutine. I have a damage variable in my subroutine, which according to the calculations is updating in a correct way. But my problem is that SDEG is not updating, hence the elements are not being deleted. I have called the STATUS variable and that is also not updating. Can anybody provide some help?
