Problem physics- shallow truss element-Non linear FEM
I have got a shallow truss element-same as in Crisfield’s book.
I have a truss configuration as in the attached file (simple 1 member as in Crisfield as Bathe) . I have a load W = 42 units applied (the force causes compression in the member).I have used incremental approach wherein the laod is applied in 6 increments of 7 units each.
