What is a valid method to simulate in ABAQUS the relaxion of a viscoelastic material (bone) after it's stressed post prosthesis insertion?

Hello everyone, I am willing to simulate(ABAQUS) the process of implanting a prosthesis in a hip bone. This process generates stress around the implanted zone, with some elements surpassing the...

How to measure camera angle in Digital Image Correlation (DIC) equipment(ARAMIS)?

Hi all, I'm working with DIC aiming to validate an FEA model. I've experienced problems in the setup of my experiment as I have been unable to point the sensors (camera cross) to the laser point...

How to align a hemipelvis for biomechanical testing which simulates a person whilst one leg standing?

Hi all, I have a specific question for performing a biomechanical test using a quasi-static machine on a hemipelvis. I have read many papers about biomechanical testing of the hemipelvis and I...

Why does Von Mises stress vary significantly in two models with same boundary conditions in ABAQUS?

I am currently modelling a load being applied in the joint zone of a hemipelvis, which correspond to a person while one leg standing. Previously, I validated my model with an already existent one...

Why is it necessary to have a finer mesh when calculating von Mises stress compared to Contact Pressure in ABAQUS?

I am working with cartilages that are in contact on the hip. In order to obtain a contour plot of the contact pressure I performed a mesh sensitivity test by selecting linear tetrahedral elements...

How to fix convergence problem in ABAQUS for a frictionless contact geometry?

Hi all, I'm trying to simulate a static load being applied into a hip geometry where femur bone (sphere geometry) and pelvis bone(hemisphere geometry) are having contact through a frictionless...

What is a valid technique for virtually reaming an acetabulum for an uncemented cup implantation?

Hi, I am currently struggling to virtually ream an acetabulum from a segmented hemipelvis. This is required for an implantation of an uncemented cup. As my analysis involves FEA (ABAQUS), I am...
