+ P/t |

Where α β_{x} and β_{y} depend on ratios a / b and P / P_{E} where:

Deflection:

Symbols used:

E =
Modulus of Elasticity (N/m^{2}, lbs/^{2})

q = Applied Load or Force to Flat Area of Plate (N/m^{2}, lbs/^{2})

P = Tension or Compression to Short Edges (N/m, Lbs/in)

v = Poisson’s ratio (assumed to be 0.3)

t = plate thickness, (m, in)

a = plate length, (m, in)

b = plate width, (m, in)

σ _{max} = maximum stress, (N/m^{2}, lbs/in^{2})

y_{max} = Maximum deflection (m, in)

α = From Table A

β_{x} = From Table A

β_{y} = From Table A
