We seek to characterize the local state of deformation of the material in a neighborhood of a point P. Consider two points P and Q in the undeformed

For the uniform state of plane strain shown in the fig ure,which one(s) of the following statement(s) is(are valid?(Assume Poisson's ratio v+0)

The following stress-strain curves were obtained for dif- ferent materials subjecting the specimen to the loading path(a, b, c, d ). Which one(s) of them correspond to elas- tic material(s)

Which of the following expressions represents the rate of work done by the stresses during the deformation of a body of an arbitrary material?

一、使程序简洁、紧凑、高效 二、有效地表示复杂的数据结构 三、动态分配内存 四、得到多于一个的函数返回值

一、作用：对源程序编译之前做一些处理,生成扩展C源程序 二、种类 三、宏定义 #define 四、文件包含 #include

一、模块化程序设计 二、基本思想：将一个大的程序按功能分割成一些小模块

一、构造数据类型之一 二、数组:有序数据的集合,用数组名标识 三、元素:属同一数据类型,用数组名和下标确定
