Description: 这是一个模拟第3类模式地震波的matlab脚本。
This a collection of Matlab scripts that solve the antiplane
(mode III) earthquake dynamic problem with slip-weakening friction,
on a 1D fault embedded in a 2D homogeneous elastic unbounded medium.
The problem is formulated as a boundary integral equation
and the elastodynamic kernels are analytically derived in
the spectral domain (spatial wavenumber).
The method is explained e.g. by Morrysey and Geubelle (1997),
and has been improved and extensively used by Nadia Lapusta,
Alain Cochard, etc.

Description: 该程序主要针对三角形问题，通过输入三角形三条边的取值范围，自动生成边的测试值，并对测试值是否能构成三角形、是否等边三角形、是否等腰三角形、是否直角三角形进行了判定与显示。其中在测试值的生成方式上，采用了两种自动生成方式：一是健壮性测试（所谓的七点法），二是边界值分析（也即五点法）。-The program mainly for the triangle problem, by entering the three sides of the triangle range, automatically generated test edge value, and test whether the value of the triangle pose, whether the equilateral triangle, is it isosceles triangle, right triangle conducted to determine whether and显示. Which the test value is generated, using two types of automatic generation methods: First, robustness testing (the so-called seven-point method), and the other is boundary value analysis (that is, five-point method).

Description: A cylindrical wave expansion method is developed to obtain the scattering field for an ideal
two-dimensional cylindrical invisibility cloak. A near-ideal model of the invisibility cloak is set up
to solve the boundary problem at the inner boundary of the cloak shell. We confirm that a cloak
with the ideal material parameters is a perfect invisibility cloak by systematically studying the
change of the scattering coefficients from the near-ideal case to the ideal one. However, due to the
slow convergence of the zeroth order scattering coefficients, a tiny perturbation on the cloak would
induce a noticeable field scattering and penetration. Platform: |

Description: 关于最新的边界元快速算法的专著，提出了一种代数方法来加快边界元方程组的求解。值得一看。-Boundary Element Methods (BEM) play an important role in modern numer-
ical computations in the applied and engineering sciences. Such algorithms are
often more convenient than the traditional Finite Element Method (FEM),
since the corresponding equations are formulated on the boundary, and, there-
fore, a signifi cant reduction of dimensionality takes place. Especially when the
physical description of the problem leads to an unbounded domain, traditional
methods like FEM become unalluring Platform: |

Description: FEMOD1 is an interactive program for the setup, solution, and printout of a two point boundary value problem in a one dimensional region. The finite element method is used.
The differential equation has the form:
-d/dX ( K(X) dU/dX ) + C(X) * dU/dX + B(X) * U = F(X) + P(X)
Here, P(X) stands for a point load function.
The boundary conditions at the end points may have one of the following forms:
U(X0) = value1
K(X0) * dU/dX(X0) = value1 * U(X0) + value2.
