[下载][Tool][软件] OSMatTest: OpenSees Material Test [OpenSees单轴材料测试工具]

[App]OpenSees Material Test.A small program to test the uniaxial materials in OpenSees.OpenSees Material Test将OpenSees ( Open System for Earthquake Engineering Simulation )中常用的单轴本构关系(钢及混凝土本构)提取出来,通过自行设计的界面进行测试,为今后更加深入的研究奠定基础。

OpenSees Concrete04 Material Test

Concrete04受压部分的包络线采用Popovics (1973) 提出的单调荷载下的应力—应变关系,并根据Karsan-Jirsa加卸载准则确定其加卸载刚度(线性);受拉部分的包络线由线性上升段和指数下降段组成,其加卸载与再加载刚度取其与原点的割线刚度。(Concrete is a uniaxial Popovics concrete material object with degraded linear unloading/reloading stiffness according to the work of Karsan-Jirsa and tensile strength with exponential decay.)
