Week 5 Sphere pressing on a plate

Aim-To get the plastic deformation of the plate.

Objective- Pressing the plate by through the sphere by displacing towards the plate.

Procedure-

1.We frst apply add tsailnless steel nonlinear to the engineering data.

2.Since the model is symmentry hence we take oneforth model so to reduce the computional time.

3.We rename the as sphere and the palte and we add material to the palte as stainless steel non linear.

4.we take symmentry one is along the z axies and one along the xasies.

symmentry about z axies

symmentry about x axiex

5.we apply the frictional contact since we want to observe the plastic deformation on the plate hence we will take plate as tearget since its has less stifness and thesphere as the contact and of frictional factor of .74.

6. we the default mesh isze on the whole body.

7.since we want to obervae plastic deformation hence we provide dispalcement as (-2,-3,0,0) by these values first tha plate dispalcesto the value of 2 nad 3 in -ve y direction and returns back to the orignal position so we can deformation of the palte after removal of the load and we provide fixed support to the palte.

8.we solve for the equiavlent stress,Directiona; deformation along the y axies and the euinqlant strain on the sphere and stress on the plate.

conclusion - we can observe the even removal of the load the palte not regained to its original position hence it attined plastic deformation.
