Large deflection, BEAM6G1

: Problem description: The cantilever beam shown is subjected to uniformly distributed loading l_y per unit length and the end force F_x, F_y. Perform a large displacement analysis under plane stress conditions and compare the results with the linear solution II.1 .

Mesh: Four quadrilaterals--see appendix A.1.

Material properties: $E=2\times 10^5$ MPa, $\nu=0.3$ .

Support: Clamped at x=0. Statically determinate.


u=v=0 node:	 1 
u=0 nodes: 	 2 11

Loading: Given as


l_y=-100 unit: N/m 
F_x=20000 F_y=-20 unit: N

Solution: The input of the distributed loading and the concentrated force is described in example II.1. It should be noted that the nonlinear solution signifficantly differs from the linear one.
