Simpleware Case Study: Total Hip Replacement Implant Positioning

Submitted by Simpleware on

Positioning hip implants poses a number of challenges, particularly in terms of getting bone and implant contact right. While experimental testing can be costly, image-based modelling can be very effective at predicting the best and worst positions for implants. 

Lagrange Multipliers in Multi-body Finite Element Code

I'm working on a Multibody dynamics code using the finite element method to simulate the behaviour of flexible beams (using this paper if anyone is interested/ it is relevant). I'd like to model joints, and as I only need spherical friction free joints I believe this should be easy using Lagrange multipliers.

When I run the code, the two bodies part company immediately. Any ideas where I'm going wrong? I'm just simulating a double pendulum with 10 elements in each body for now.

Constitutive modeling of hyperelastic solids reinforced by spheroidal particles under large deformations

Submitted by rezaavaz on

This paper presents a homogenization-based constitutive model for the mechanical behavior of particle-reinforced elastomers with random microstructures subjected to finite deformations. The model is based on a recently developed homogenization method (Avazmohammadi and Ponte Castaneda 2013; J. Elasticity 112, 1828–1850) for two-phase, hyperelastic composites, and is able to directly account for the shape, orientation, and concentration of the particles.

To the Editors of EML

Submitted by unsrohith on

Dear Editors,

The first step of starting EML looks promising and with the help of academic people in this community, I think EML has generated enough heat with lots of interesting view points.

We all know that there has been lots of discussion in the imechanica community regarding open source journals, had any one thought about making EML fully open source?.

Thanks and Regards,

Rohith

Simpleware Case Study: Evaluating Wheelchair Cushion Designs

Submitted by Simpleware on

In this study, researchers at Tel Aviv University and ROHO Inc. analysed how wheelchair cushion design affects the risk of pressure ulcers. MRI data of a male subject was used to generate a robust 3D model in Simpleware software for Finite Element Analysis (FEA) of stresses in FEBio. Comparisons were made between different types of wheelchair cushions to determine how they respond to pressures. The study was successful at evaluating the effectiveness of FE modelling for studying interactions between wheelchair users and equipment.
