有限元分析的matlab代码- 结构 本书旨在为读者提供一些有限元的matlab代码。 在简短介绍MATLAB之后，这本书说明了有限元。 用简单的脚本和函数实现一些问题。 .离散系统，如弹簧和杆 .梁和框架在二维和三维中的弯曲 .平面应力问题 .弯曲板 .Timoshenko明德林梁和板的自由振动，包括叠层复合材料 .Timoshenko梁和明德林板的屈曲(MATLAB Codes for Finite Element Analysis- Solids and Structures This book intend to supply readers with some MATLAB codes for finite element analysis of solids and structures. After a short introduction to MATLAB, the book illustrates the finite element implementation of some problems by simple scripts and functions. The following problems are discussed: .Discrete systems, such as springs and bars .Beams and frames in bending in 2D and 3D . Plane stress problems .Plates in bending .Free vibration of Timoshenko beams and Mindlin plates, including laminated composites .Buckling of Timoshenko beams and Mindlin plates)

说明：  根据传统材料力学势能法来进行数值分析计算健康齿轮时变啮合刚度(Calculating the time varying mesh stiffness of perfect gear based on potential energy method)

Addressbook using double-linked list. This example shows the use of a double-linked list by implementing an addressbook for the console. It has features like inserting, searching(linear), sorting(bubble sort), deleting and load/save to a file. I wrote this during my study of Applied Computer Science so it s intended mainly for students who want to know about some advanced programming techniques in C. The Code was compiled with MSVC++ 6.0 but it should compile with any ANSI-compliant compiler.
