Comparison of Hand Calculation with SOLIDWORKS Simulation


Hand Calculation:

The figure 1 which shown below is a plate with hole in the middle fixed at one end and in other side load is applied.

Parameters
Plate Module
Length(L)
60 mm
Width(w)
40 mm
Thickness(T)
1mm
Plate area(Ap)
40 mm2
Hole area(Ao)
78.5 mm2
Elastic Modulus(E)
2e+5 N/mm2 (AISI 1020)
Force (F)
200 N


Nominal stress:

σnom = F/(w-d)t= 2000/(40-10) = 66.666 N/mm2

Stress concentration:

Kt = σmax/ σnom

σmax= 2.5 * 66.666 = 159.99 N/mm2
