Per. Roarks Formulas for Stress and Strain for flat plates with straight boundaries and constant thickness
Rectangular plate; one edge fixed, opposite edge free, remaining edges simply supported loading distributed line load w lb/in along free edge.
Rectangular plate; one edge fixed,
opposite edge free, remaining edges simply supported. |
Uniformly decreasing
from fixed edge to zero at 2/3 b. |
Stress and Reaction Force at center of fixed edge:
and | R = γ1w |
Stress and Reaction Force at center of free edge:
and | R = γ2w |
Symbols used:
w = Applied Line Load or Force to Flat Area of Plate (lbs/in2)
v = Poisson’s ratio (assumed to be 0.2)
t = plate thickness, ( in)
a = plate length, ( in)
b = plate width, (in)
σ = stress, (lbs/in2)
R = Reaction force per unit length (lbs/in) normal to the plate surface exerted by the boundary support on the edge of the plate.
