ANSYS常用单元类型
ansys常用单元类型如下几种：
1、线单元：用于单个单元上应力为常数的情况
2、梁单元：用于螺栓、薄壁管件、C型截面构件、角钢或细长薄膜构件等模型
3、杆单元：用于弹簧、螺杆、预应力螺杆和薄膜桁架等模型
4、弹簧单元：用于弹簧、螺杆，或细长构件，或通过刚度等效替代复杂结构等模型
5、壳单元：壳单元用于薄板或曲面模型。壳单元分析应用的基本原则是每块面板的尺寸不低于其厚度的10倍

I found by accident that the following compiles: #include <string> #include <iostream> class A{ int i{}; std::string s{}; public: A(int _i, const std::string& _s) : i(_i), s(_s) { puts("Called A(int, const std::string)"); } }; A foo(int k, const char* cstr){ return {k, cstr}; // (*) } int main(){ auto a = foo(10, "Hi!"); return 0; } The line of interest is (*). I guess the function foo is equivalent to: A foo(int k, const char* str){ return A(k, cstr); } However, is there a special name for this mechanism in (*)? Or is it just the simple fact that the compiler knows which constructor to call due to the return type?
