Four single element tests of CDPM2
A single tetrahedron with one Gauss point, four monotonic loadings (tension, compression, simple shear, pure shear). Anyone implementing CDPM2 can test against those as a start. Reproducible in one Docker command.

The aim of our research at the James Watt School of Engineering at the University of Glasgow is to understand, predict and improve the response of concrete and concrete structures. Our work is focused on deterioration processes, development of new materials, optimisation of material use, repair and strengthening techniques, and response of structures subjected to accidental loading. Currently, our methodologies comprise the following areas: Meso/Micro scale modelling, Constitutive modelling and Structural modelling. We contribute to the development of the finite element program OOFEM. You can find all our models implemented in our github fork of OOFEM. Our results are described in our publications.
