| Abstract: |
| Based on the open finite element software system SiPESC.FEMS,according to the theory and process of nonlinear finite element analysis,a new general software framework for rate-independent small strain elasto-plastic analysis is constructed by using object-oriented programing and software design patterns such as factory pattern and builder pattern.The framework abstracts data model class,algorithm and algorithm parameter classes based on the idea of the separation of algorithm and data model,to support the dynamic substitution and assembly of individual functional modules with open and scalable attributes.Meanwhile,based on the data processing ability of the engineering database on SiPESC platform,the elasto-plastic analysis can access a large amount of historical data by universal interface and management mode,and provide efficient and stable support for large-scale problems.The framework's validity and flexibility can be demonstrated by numerical examples with diverse solid elements,various constitutive models and different problem scales. |
