Stress and Reaction Force
Reaction Force
Stress and Reaction Force at x = ± a/2, z = 0.4b if a ≥ b or z = 0.2b if a < b
Reaction Force
Where used:
E = Modulus of Elasticity (lbs/in2)
q = Total load or force to Plate (lbs/in2)
v = Poisson’s ratio (assumed to be 0.3)
t = plate thickness, (in)
a = plate length, (in)
b = plate width, (in)
σb = stress, (lbs/in2)
R = Reaction Force (lbs/in)
