Fiber Element

With Isoparametric beam element,we need to input the following data.

• the length of Rigid partλg1,2　and Fiber part λf1,2,3,4
• Cross section A
• Young Ratio E
• Poisson Ration ν
• Second Moment of Cross Section for all direction (Ip,Iy,Iz)

For the Rotation we assume that the twist angle θx is always zero.
