用晶闸管建立的12脉动特高压直流输电模型(12 pulse HVDC model based on thyristor)

ABAQUS 有限元子程序，粘弹性本构，蠕变应力松弛测试拟合结果 cohesive 粘接单元，用于分层分析的子程序，帮助初学者快速掌握ABAQUS的内聚体单元应用(ABAQUS umat creep stress relaxation fitting result Cohesive bonding unit, used for hierarchical analysis of the subroutine, to help beginners quickly grasp the ABAQUS cohesive unit application)

说明：  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.)

节点度是指和该节点相关联的边的条数，又称关联度。 特别地，对于有向图， 节点的入度 是指进入该节点的边的条数; 节点的出度是指从该节点出发的边的条数。(Node degree refers to the number of edges associated with the node, also known as the degree of association. In particular, for a directed graph, The ingress of a node is the number of edges entering the node; The out-degree of a node is the number of edges that start from that node.)

说明：  通过设置不同的参数，创建小世界网络，用于仿真建模。(This program is to create a small world network for simulation.)

说明：  使用matlab进行超声波阵列指向性仿真(Simulation of directivity of ultrasonic array using MATLAB)

These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to verify and apply the Puck Failure Criteria using the commercially available finite element package ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented with different post failure degradation schemes EWM/CSE.
