MUESLI - a Material UnivErSal LIbrary

Abstract This article describes MUESLI , an open source library with constitutive models of continuum materials for solid, fluid, and thermal problems available at http://www.materials.imdea.org/Muesli . The library is object oriented, and includes the most commonly employed material models in Computational Mechanics. It is designed for easy extension, and includes classes for tensor manipulation and automatic testing. The library can be linked to existing codes, including commercial ones, for some of which specific interfaces are provided.
