Week 1 Stress Concentration on a Plate with hole

AIM:-To perform linear analysis for plate considering the hole in it.

THEORY:-

PROCEDURE:-

• Open the Ansys workbench and click on static structural

• Selecting analysis type as static structural

• After selecting that we need to specify the data like material, geometry, etc...
• To specify the material we need to double click on engineering data

• To specify the new material we need to select the engineering data source.
• And we need to select the material and we need to click on the + symbol to add to material data.

• To check whether the material is created or not we need to go to filter engineering data

• Now material creation is completed so, we need to create geometry
• To create geometry we had two cad software one is design modeler and space claim
• We can use any of them
• I am choosing a space claim modeler to create the geometry

• Then we will enter into the space claim window by using the geometry creation tools and create a geometry

• By using the pull option extrude the surface
• To measure the dimension we need select the shift and the points

• After creating the geometry we need to go to the mesh module '
• There we can find the option as mesh and give mesh size as six and click generate mesh

• Then we need to give boundary conditions to the component
• To give we need to go to loads and select the faces and give bcs

RESULTS:-

• This total deformation for case 1
• The max deformation is 0.000442 mm
• The deformation is pretty enough

• This total deformation for case 2
• The max deformation is 0.000446 mm
• The deformation is a bit higher than case 1 but it is enough

• The component of case 1 has maximum stress as 0.923 Mpa

• The component of case 2 has maximum stress as 0.87076 Mpa

JUSTIFICATION:-

• As we can see both components having the same deformation values and minute change in stress mass
• Both components are safe we can use them for design
• But if we consider the stress concentration factor then design 2 is best the stress is distributed to the holes
• If consider the production cost we can take case 1 there no much difference it is negilabel
• The factor of safety of component is high compared to case 1 but both are safer
