Peak load in rapid compression tests: experiments and micromechanical modelling

Developments in micromechanical modelling of granular materials

We are honouring the memory of Ioannis Vardoulakis through this special issue of Granular Matter, which is devoted to developments in micromechanical modelling of granular materials. Ioannis Vardoulakis will be forever remembered as an innovative experimentalist, a brilliantmechanician, an enthusiastic scientist, a devoted teacher, and above all an exceptional human being. The impression he mad...

Micromechanical study of the load transfer in a polycaprolactone–collagen hybrid scaffold when subjected to unconfined and confined compression

Scaffolds are used in diverse tissue engineering applications as hosts for cell proliferation and extracellular matrix formation. One of the most used tissue engineering materials is collagen, which is well known to be a natural biomaterial, also frequently used as cell substrate, given its natural abundance and intrinsic biocompatibility. This study aims to evaluate how the macroscopic biomech...

Numerical micromechanical modelling of brittle polycrystalline materials

A generally applicable framework for generating a nite element mesh that is based on the actual micro-structure of a material is developed. The procedure is applied to a microscopic image of a ceramic material. Special attention is paid to the modelling of the interfaces between adjoining grains. Plane strain and plane stress nite element calculations are performed. The observed e ective consta...

Peak Power Analysis and Modelling

Database engines often consume significant power during query processing activities especially during complex query processing, which is motivating researchers to investigate the redesign of their database internals to minimize the energy overheads. While the prior literature has dealt exclusively with average power considerations, our focus here is on peak power consumption. We begin by profil...
