Fortran programs and Abaqus subroutines: Higher-order and higher precision numerical approximations of finite strain elasticity moduli

  • Stephen John Connolly (Creator)



This dataset contains Fortran programs and subroutines for analytical and approximate implementations of hyperelastic constitutive models in terms of the first invariant of the left/right-Cauchy-Green tensor. The approximation methods are novel in that they exploit higher-precision arithmetic (quadruple precision) and higher-order approximations. The programs may be used to assess the elasticity moduli outwith Finite Element simulations, for the purpose of debugging or numerical study. The user-subroutines may be directly used (by advanced users) within Abaqus/Standard, having been tested with: Abaqus/Standard v2016, Microsoft Visual Studio 2010 and Intel Parallel Studio XE 2013.
