Treffer: Onset App

A customised Abaqus CAE Application incorporating Onset Theory Reliable failure prediction of fibre reinforced polymer composite materials is a challenging and on-going research endeavour. Strain Invariant Failure Theory, also known as Onset theory, is a fundamentally novel multi-scale modelling approach in predicting the matrix failure of composites and thus help achieve a step-change in the cost of developing and certifying composite structures. Several micromechanical finite element models have been developed in the process of extending Onset Theory to various forms of composite architectures at the University of New South Wales as part of the Boeing sponsored Australian Research Council (ARC) Linkage Project (LP), LP150100653. For easier adoption by The Boeing Company, Python and Fortran scripts for building and analysing the finite element models of fibre reinforced composite materials and structures need to be packaged and implemented into a streamlined graphical user interface (GUI). Hence, a customised application of Abaqus CAE, a finite element software tool widely used at The Boeing Company and its subsidiaries, is developed incorporating the Onset Theory and will be referred to as ‘Onset App’. The software source code is written in Python language and is developed using Abaqus GUI Toolkit in Abaqus/CAE version 2020 on Windows 10 OS platform. The Abaqus GUI Toolkit is an extension of the FOX GUI Toolkit, just as the Abaqus Scripting Interface is an extension of the Python programming language. FOX, which stands for Free Objects for X, is a modern, object-oriented, platform-independent GUI toolkit. As such, the source code is version and platform agnostic and most features1 of the application should be able to work with previous or future versions of Abaqus/CAE and run on all supported platforms of Abaqus/CAE although this has not been tested at this stage.
