This folder contains the implementation of the benchmark problems for cardiac mechanics described in the paper:
Land, S., Gurev, V., Arens, S. et al. Verification of cardiac mechanics software: benchmark problems and solutions for testing active and passive material behaviour. > Proc. R. Soc. A 471, 20150641 (2015).DOI: 10.1098/rspa.2015.0641
The benchmark suite consists of three problems of increasing complexity designed to verify the implementation of passive and active cardiac mechanics solvers.
Deflection of a beam made of anisotropic material under a pressure load. This problem tests the implementation of the transversely isotropic constitutive law (Guccione model) and the handling of Neumann boundary conditions (pressure).
Inflation of an idealized Left Ventricle (truncated ellipsoid) made of isotropic material. This problem tests the handling of curvilinear geometries and large deformations under pressure loading.
Inflation and active contraction of the idealized Left Ventricle with a spatially varying fiber architecture. This problem tests the coupling between the passive anisotropic material, the active stress model, and the fiber field definition.
