说明：  书籍扫描件，fortran使用手册，清晰扫描版(this is a book for these who want to use fortran language)

ABAQUS UMAT; Drucker-Prager; 随动硬化The development of a pressure-dependent constitutive model with combined multilinear kinematic and isotropic hardening is presented. The constitutive model is developed using the ABAQUS user material subroutine (UMAT). First the pressure-dependent plasticity model is derived. Following this, the combined bilinear and combined multilinear hardening equations are developed for von Mises plasticity theory. The hardening rule equations are then modified to include pressure dependency. The method for  implementingthe new constitutive model into ABAQUS is given. Finally, verification

a program which analyzes a 2D fluid flow using the reduced basis method

说明：  Code-Aster是目前比较权威、严谨的有限元分析开源软件，全名为Analysis of Structures and Thermomechanics for Studies and Research，由法国EDF公司开发，包含静力学分析、动力学分析、线性/非线性分析、断裂分析等，支持力、热、流等多物理场耦合模拟。该手册对Code-Aster功能进行了详细说明。(Code aster is a relatively authoritative and rigorous open-source software for finite element analysis. Its full name is analysis of structures and thermomechanics for studies and research. It is developed by EDF company in France, including statics analysis, dynamics analysis, linear / nonlinear analysis, fracture analysis, etc., and support force, heat, flow and other multi physical field coupling simulation. This manual gives a detailed description of the code aster function.)
