基于ANSYS分析平台的铰接薄壳的后屈曲分析--APDL(Post-buckling analysis of articulated thin shells based on ANSYS analysis platform--APDL)

说明：  用于abaqus里形状记忆合金材性模拟的子程序umat文件(an umat file used to simulate SMA in ABAQUS)

说明：  ansys fluent udf 定义空气物性(Definiting air physical properties by UDF)

对于非线性模型的跟踪预估问题，摒弃额对非线性函数进行线性化的做法，采用无迹变换处理均值和方差的非线性传递问题。(For the tracking and prediction problem of the nonlinear model, the linearization of the non-linear function is abandoned, and the traceless transformation is used to deal with the non-linear transfer of mean and variance.)

说明：  固定翼无人机跟踪地面目标，速度范围25-50，离散式计算(target tracking by fixed-wing uav)

说明：  udf算法，FLUENT模拟定义，在不同时间变热流密度下进行用户自定义设置(Temperature UDF algorithm)

说明：  生成三维随机纤维的matlba程序，可以直接使用(The matlba program for generating 3D random fibers can be used directly)

说明：  六边形蜂窝自动建模插件，能在abaqus中自动建立蜂窝模型(Hexagonal honeycomb automatic modeling plug-in)

用于ABAQUS软件的子程序，可对金属材料的韧性断裂行为进行精确的计算，并预测其断裂行为。(The subroutine for ABAQUS software can be used to calculate the ductile fracture behavior of metal materials accurately and predict the fracture behavior.)

稳健波束形成中的mvdr（最小方差无畸变失真响应）算法(robust adaptive bearforming mvdr)
