E = 30 x 106 psi
ρ = 0.000728 lb-sec2/in4
υ=0 Geometric Properties
t = 1 in
b = 2 in
= 16 in Analysis Assumptions and Modeling Notes
The problem is solved in two different ways:
• Using Elastic Shell Elements (SHELL63) • Using 3-D Solid Shell Elements (SOLSH190) All lateral master degrees of freedom (MDOF) are selected along the plate centerline. The area is meshed with
4 elements along the X axis and 2 elements along the Y axis. Poisson's ratio is assumed to be zero. Results Comparison
