Brittle cracking in brittle materials
Hi there,
I am trying to simulate a crack opening process in ABAQUS. I start up from a simple model of plate with a notch subjected to tension. I would like to see the crack opening. To model a brittle mnaterial behaviour I have added a brittle cracking with sub-option brttle failure and brittle shear.
Please look at dat file:
*Heading
*Node
*Element, type=CPS3
*Element, type=CPS4R
*Nset, nset=ASSEMBLY_PART-1-1__PICKEDSET2
*Elset, elset=ASSEMBLY_PART-1-1__I1
Abaqus Laterally loaded piles
Hi all,
I modelled a pile in sandy soil, the pile is subjected to a lateral load. I embedded the pile inside the soil. The soil if always over stiffened , can any one tell me why , why the soil is very very stiff, I used very small value for elasticity modulus. please help
Modeling of Viscoelasticity with Hypoelasticity constitutive equations
Hi all,
I'm trying to model high temperature viscoelasticity using hypoelastic constitutive equations. I'm not sure of how to include the rotation tensor in the generalized viscoelastic equation.
kindly advise me.
Thank you very much.
Objective Stress Rates in Finite Strain of Inelastic Solid and Their Energy Consistency
In many practical problems of solid mechanics, it is sufficient to characterize material deformation by the small (or linearized) strain tensor. But there are also many problems where the finiteness of strain must be taken into account.
Ph.D. Position at Polytechnique Montreal on Instability-Assisted Microfabrication of Tough Fibers
A funded Ph.D. positionin Mechanical Engineering is available at Polytechnique in Montreal, Canada. The work combines experimentations and theoretical modelling. The goal of the project is to use a fluid instability to fabricate intricate patterns at the microscopic scale. By fabricating fibers this way, interesting mechanical properties can be obtained depending on the parameters of the instability.
