Description: 有序无序转变的计算机模拟——MC算法
一个样品做实验，从低温有序相，逐渐升温，到高温无序相。
模型假设：
1 模拟三维简单斜方，AB型合金，共有M*N*L个原子；
2 最邻近假设，即只考虑最邻近原子之间的相互作用，次邻近和更远的原子之间的作用忽略（误差较大），
，在简单斜方中，最邻近原子数z=6；
3 只考虑势能的作用，AA，BB，AB原子间的作用用Eaa,Ebb,Eab=Eba表示 且忽略振动能（原则上，温度很高时，不能忽略）等；
4 各原子之间的相互作用独立，即各化学键相互独立；
5 边界原子任然周期排列，只不过，邻近原子数减小，能量较高；边界面上的原子z=5；线
上的原子z=4，顶点上的原子z=3；由于顶点上只有四个原子，算法中不考虑这种情况；
6 其它假设。- Order-disorder transition of computer simulation- MC algorithm a sample experiment, from the low-temperature ordered phase, gradually warming up to a high temperature disordered phase. Model assumes that: 1 of three-dimensional rhombic, AB-type alloy, a total of M* N* L atoms 2 nearest the assumption that only consider the interaction between the neighboring atoms, and further sub-adjacent atoms ignore the interaction between the (larger error), , in the simple oblique Fang, nearest neighbor atoms, z = 6 3 only consider the potential role, AA, BB, AB interatomic with Eaa, Ebb, Eab = Eba representation and ignore the vibration energy (principle, the temperature is high, it can not be ignored), etc. 4 each atom interactions between independent, which means that each bond independently 5 boundary periodic arrangement of atoms in any course, but , adjacent atoms decreases, the higher energy boundary atomic plane z = 5 atoms on line z = 4, the vertex atoms z = 3 only four

Description: These codes simulate model C for a dilute alloy (one order parameter and one thermal field), as described in the text. They are structured in modular form, and students an encouraged to build more complex codes using this structure. The file "manager.f" is the highest level of control, co-ordinating, so to speak, the sequence to calls to to solvers, initializations, etc. The module solver_mod.f90 contains the solver routines. The module util_mod.f90 contains functions called upon to do various i/o
To compile the codes into an executable, type: "make"
To run, type ./<name_of_executable

Description: In order to actually describe the mechanical behavior of phase transformation and plasticity for NiTi shape memory alloy (SMA), the master equations which based on irreversible thermodynamics theory was derived by assuming two internal variables to characterize phase transformation evolution and plastic evolution. Thus a unified constitutive model was developed by summarizing master equati
