Analysis on a plate with a hole using SOLIDWORKS
AIM
Perform a static analysis on two models of plate with holes. You will have to create the model in Solidworks and perform the analysis.
CASE 1
Length=300mm
Height=120mm
Thickness=30mm
Circular Hole at the center:
Diameter=60mm
CASE 2
Length=300mm
Height=120mm
Thickness=30mm
Circular Hole at the center:
Diameter=60mm
- Two holes of 30 mm diameter which are placed 90mm away from the central hole on both sides.
- Apply a fixed relation to one of the short side of the plate and apply a force of 1000N on the other such that the plate is stretched.
- Run the analysis and compare the results for stress, strain and displacement
CASE 1:
Part Model:
Dimensions:
Length: 300mm
Height: 120mm
Thickness: 30mm
Hole Diameter: 60mm at the center of the plate surface
Material of Plate:
Alloy Steel
Density: 7700 kg/m^3
Poisson Ratio: 0.28
Loading and Fixing:
Tensile Load: 1000N
Support: One face fixed supported
As per the loading condition defined in the challenge, one face of the plate is fixed. i.e all the 6 degree of freedom restricted and a tensile load of 1000N is applied perpendicular to the othe face.
Mesh Detail: Standard Mesh
Element Type: Solid Mesh
Element size: 7 mm
Number of Elements: 18335
Number of Nodes: 4059
RESULT:
Stress:
Maximum Stress= 938728.69 von misses N/m^2
Minimum Stress= 81883.34 von misses N/m^2
Dispalcement:
Maximum Displacement: 0.000515 (URES) mm
Strain:
Maximum Strain:0.000004 ESTRN
CASE 2:
Part Model:
Dimensions:
Length: 300mm
Height: 120mm
Thickness: 30mm
Hole Diameter: 60mm at the center of the plate surface, Two 30mm at 90mm offset from the centre on both sides.
Material of Plate:
Alloy Steel
Density: 7700 kg/m^3
Poisson Ratio: 0.28
Loading and Fixing:
Tensile Load: 1000N
Support: One face fixed supported
As per the loading condition defined in the challenge, one face of the plate is fixed. i.e all the 6 degree of freedom restricted and a tensile load of 1000N is applied perpendicular to the othe face.
Mesh Detail: Standard Mesh
Element Type: Solid Mesh
Element size: 7 mm
Number of Elements: 18549
Number of Nodes: 4127
RESULT:
Stress:
Maximum Stress= 915840.56 von misses N/m^2
Minimum Stress= 39038.79 von misses N/m^2
Dispalcement:
Maximum Displacement: 0.000553 (URES) mm
Strain:
Maximum Strain:0.000004 ESTRN
CONCLUSION:
- The 2 rectangular plates have very similar characteristics as far as maximum Von-Mises stresses, maximum strain and maximum displacement are considered.
- The plate with 3 holes has an almost negligibly higher displacement value by the order of 0.00005 mm.
- The plate with one hole experiences more stresses and this leads us to conclude that the increased number of holes act as stress relief features.
