Hi All
As shown in the attached image, I have a simply supported beam with a load of 150kN acting at the center of the beam span.
E = 210 GPa
rho = 7800 kgm-3
span = 250 mm
After solving this in FE solver, I got maximum displacement to be ~4mm (at node 52)
But, on using the theoretical relation of delta = P* l^3 / (48*E*I), it is about ~11mm.
Can somebody please help me on this ? how to co-relate this.
Some observations:
1. There is no hourglassing.
2. Beam looks compressed by about 0.8mm at the center at the end of solution.
