Let's say I have a strain energy density function W = W(I1,I2) + W(I3).
The second PK stress is then defined as S_{ij} = ∂W/∂E_{ij} and the constitutive tensor C_{ijkl} = ∂/∂E_{kl}(∂W/∂E_{ij}).
If I want to verify that I'm deriving the correct analytical constitutive and stress tensor...
I am trying to model the slip and separation between a Nuclear reactor and soil when hit by a bi-directional earthquake using the interaction feature.
The interaction that I am trying to model is as follows:
Normal - Stiffness acts only when the surfaces are in compression and there is no...
Hi all
I am modeling the slip and separation of a structure resting on soil in 2D when affected by both transverse and vertical TH of an EQ.
I am using interaction properties as mentioned below:
Tangential: Penalty -> Coeff of Friction, Shear Stress limit, maximum elastic slip
Normal: Linear ->...
To test out friction in ABAQUS, I tried to model the interaction between two blocks in 3D, the smaller one(1x1x5)resting on the Larger one (10x10x10) with both having a mass density of 1000 kg/m3.
The interaction was defined as follows:
Tangential Behaviour - 0.7 (friction coefficient using the...
Hi
I am modelling a lumped mass model of the outer shell of a Nuclear Containment Structure given in a research paper.It is a hollow cylinder with a dome placed on top.
To find out the total lateral stiffness, I applied a Unit displacement at the topmost node of the structure and checked the...
