Abstract

Abstract

Ecological composite wall structure is always in complex stress state in the loading process, and using wallinner filling material has diversity．The use of a single kind of compound material model can't reflect well the stressof the filled various materials．By using the second developed function of the nonlinear finite element softwareABAQUS, the twin shear unified strength theory compound model applicable to any kind of material is embedded intothe software, and the nonlinear analysis is carried out for ecological composite wall structure．The results show thatwhen the twin shear unified strength theory compound model is added to ABAQUS, material cell library is enriched, thus improving the computational accuracy and efficiency．Through the example, the UMAT ( user-defined materialmechanical behavior) can not only make full use of the powerful nonlinear solution platform of the software ABAQUS, but also can do complex finite element numerical analysis for ecological composite wall structure, with some accuracy, economy and applicability in practical engineering
