SPH 源代码，用于科研计算，是光滑粒子流体动力学-一种无网格粒子法书后的源代码(SPH source code, for scientific computing, is a smoothed particle hydrodynamics -- a source code after a meshless particle method.)

混凝土收缩徐变， 多用于结构分析和混凝土结构施工阶段计算(Concrete shrinkage and creep are mostly used for structural analysis and concrete structure construction stage calculation.)

本文主要介绍利用 Fortran 调用 Matlab 函数程序的几种方法。Fotran为什么要调用Matlab呢？这主要是利用Matlab中函数的丰富性弥补Fortran编程语言，这样就可以比较高效地开发所需要的算法。

弹粘塑性本构模型出发，考虑混凝土材料的损伤，推导提出混凝土弹粘塑性损伤本构模型，适用性强大。本模型能够反映出材料不同的拉压性能、材料的应变率敏感性、静水压力及中间主应力的影响，具有一定的实用价值。(Based on the constitutive model of the elastic viscoplastic constitutive model, the damage of concrete materials is considered, and the constitutive model of concrete elastic viscoplastic damage is deduced. This model can reflect the influence of different tension and compression properties, strain rate sensitivity, hydrostatic pressure and the main stress of the material, which has a certain practical value.)

塔式起重机建模文档，非常棒的商业流程和代码，可以用于ANSYS结构建模学习和工程应用实践练习，其中参数可以用户自己参考修改编写！ 此.txt文档为ANSYS的命令流（类似于ForTran）(Tower crane model documentation, great business processes and code that can be used ANSYS structural modeling study and practice of engineering practice, in which parameters can be written to modify the users own reference!)
