TO 土老帽:
GBbh ar},g z+3 9ee 1) Before you use any software, you'd better read some theoretical
R2LK.bTVn Bq!cY Wj books about finite element method for structure, for example the
A*'V+( ;fGx;D book from Tsinghua Univ. is good one.
(M`|'o! *IZf^-=Q 2) After you understand the FEM in structures(beam or truss),
XP;x@I#l d+}k g you can use some small finite element program to
Y {c5 !Iq{ 5: solve beam or some structure problems for better understanding;
