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.

Figure 1

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:

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

Stress concentration:

K_t = σ_max/ σ_nom

σ_max= 2.5 * 66.666 = 159.99 N/mm²
