Motivated by applications in orthopaedic surgery, new constitutive laws for trabecular (or spongious) bone are developed in the framework of continuum mechanics, implemented in a mechanical analysis computer program, validated by a number of in vitro exper ...
The development of a conceptual framework to test different viscoelastic constitutive laws is presented. This framework has the advantage of satisfying a priori the thermodynamic restrictions and is valid for large deformations. In addition, the different ...
This paper describes a microgripper used for the micro-assembly of an artificial scaffold for tissue engineering. The porous sponge-like scaffold is a three dimensional construct built by tiny unit parts of biodegradable polymer. This application requires ...
In this work, in order to improve mechanical stability of pseudomorphic HEMTs (PMHEMTs), we propose a pseudomorphic InAlAs/InGaAs/InP structure where the channel and the spacer are strain compensated: as in the conventional structure, the InGaAs channel is ...
Traction tests on soft tissues show that the shape of the stress strain curves depends on the strain rate at which the tests are performed. Many of the constitutive models that have been proposed fail to properly consider the effect of the strain rate when ...
The mechanical behavior of an aluminum alloy during uniaxial cyclic loading is examined using finite element simulations of aggregates with individually resolved crystals. The aggregates consist of face centered cubic (FCC) crystals with initial orientatio ...
An understanding of the behaviour of saturated/unsaturated soils is important for the design and analysis of geostructures. In this paper a continuum approach based on a structured thermodynamic theory of mixtures developed by Svendsen & Hutter (1995), in ...
