A Multi-Scale Finite Element Model of Bruising in Soft Connective Tissues.

Sutured tendon repair; a multi-scale finite element model

Following rupture, tendons are sutured to reapproximate the severed ends and permit healing. Several repair techniques are employed clinically, with recent focus towards high-strength sutures, permitting early active mobilisation thus improving resultant joint mobility. However, the arrangement of suture repairs locally alters the loading environment experienced by the tendon. The extent of the...

Hierarchical Multi-resolution Finite Element Model for Soft Body Simulation

The complexity of most surgical models has not allowed interactive simulations on standard computers. We propose a new framework to finely control the resolution of the models. This allows us to dynamically concentrate the computational force where it is most needed. Given the geometrical model of an object to simulate, we first compute a bounding box and then recursively subdivide it where nee...

Modeling Static Bruising in Apple Fruits: A Comparative Study, Part II: Finite Element Approach

ABSTRACT- Mechanical damage degrades fruit quality in the chain from production to the consumption. Damage is due to static, impact and vibration loads during processes such as harvesting, transportation, sorting and bulk storage. In the present study finite element (FE) models were used to simulate the process of static bruising for apple fruits by contact of the fruit with a hard surface. Thr...

Simulation of the Exophthalmia Reduction Using a Finite Element Model of the Orbital Soft Tissues

This paper proposes a computer-assisted system for the surgical treatment of exophthalmia. This treatment is classically characterized by a decompression of the orbit, by the mean of an orbital walls osteotomy. The planning of this osteotomy consists in defining the size and the location of the decompression hole. A biomechanical model of the orbital soft tissues and its interactions with the w...
