Lead Research Organisation:
University of Strathclyde
Department Name: Mechanical and Aerospace Engineering
Abstract
The aim of the proposed project is to develop advanced material models and Finite Element Analysis methodologies for design-analysis of elastomeric seals in industry applications, with initial focus on Oil and Gas production equipment and mineral-slurry transport applications.
The research programme will include fundamental research into the behaviour and characterisation of elastomeric materials, experimental analysis of elastomeric materials and numerical simulation and validation of critical elastomer seal configurations.
The objective of the research is to deliver better understanding of the complex behaviour of elastomeric materials, define a validated mathematical model for practical analysis and investigate the response of representative industrial sealing systems.

Description | It has been found from literature review and primary research that mathematical (constitutive) models used for accurately simulating rubber are generally not available in commercial simulation software. This finding has led to the development of open-source code to allow simple and accurate implementation of user-defined constitutive models. To develop the open-source code, a new and highly accurate method was developed and employed so that unavailable models were easier to implement. Additional studies of experimental data from literature have investigated how much experimental data is required in order to effectively simulate a rubber component. The outcome of this research defines a procedure for obtaining only necessary experimental data. This can enable a more efficient experimental programme for rubber component simulation. |
Exploitation Route | The developed implementation methods may be used for more accurate simulation of rubber components. Within these, the proposed experimental procedure would be used to ensure that the component is properly understood for simulating its behaviour with an appropriate and efficient number of experiments. |

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

Impact | The programs and subroutines contained within the dataset were used to compute numerically accurate approximated tangent moduli, which allow for the implementation of hyperelastic constitutive models within an implicit Finite Element Method. The high precision method used is to be published as a standalone paper. The methods also serves as a useful tool in developing analytically derived tangent moduli. |
