摘要

UPFs是大型通用商业有限元软件ANSYS强大的二次开发工具,为了ANSYS用户在使用UPFs进行二次开发时有更多的参考并弥补ANSYS因元非线性黏弹性本构模型而在抗震工程应用中严重受限的不足,在ANSYS中用UPFs对非线性黏弹性本构模型进行二次开发和算例验证,结合实例详细演示了用ANSYS的UPFs进行本构模型二次开发的具体过程,并对应用UPFs时所碰到的实际问题及解决办法和经验技巧进行了总结。算例验证结果表明,所开发的本构模型可使ANSYS更好地应用于岩土和结构抗震工程当中,开发的技术和经验可供UPFs用户参考。
In order to provide more references for UPFs users and break the application limitation of ANSYS in seismic area for the lack of nonlinear viscous-elastic material model,the nonlinear viscouselastic material model was developed in ANSYS with UPFs and verified by example,and the procedure of developing material model with UPFs of ANSYS is demonstrated deliberately.Additionally, the problems encountered during this developing and their solutions and technical experiences were presented.Verifying shows that the development of nonlinear viscous-elastic material model with UPFs is successful;the solutions of programming problems and techniques are effective;the nonlinear viscous-elastic material model developed by this paper can extend application of ANSYS in geotechnical and structural seismic engineering;the successful UPFs experiences can be referenced by UPFs users.
