Week 5 Sphere pressing on a plate

Aim :

To find the deformation plate when load is given on the sphere .

Software used :

Ansys work bench 2021 R2

Procedure :

The simulation is done in the static strutural module .

Model is imported from the portal and opned in the space claim .

As the model is symmentrical we use symentric option and simplify the model as 1/ 4 model reamainning is removed to reduce the computing time .

The load and displacement can be given in an uniform manner with the half model by this option .

Materials used are structural steel on sphere and non linear structural steel for the plate .

The boundry condtions are the plate is fixed on the bottom and the displacement is given on the top of the sphere on the -y axsis for 4mm

The contacts are firctional type of contact is given with 0.75 as co eff of friction .

Contact is the sphere and the target is the plate .

The sysmetric is used on x and z axsis to show its sysmentric on the both axsis and ansys will take it as a full body and show the results .

Displacemnt is given in 4 steps and only in y axsis remaining is free .

We insert equvalent stress and strain then directional deformation on y axsis .

Then slove it .

Result:

As per the question we have done the sphere on the plate and found deformation on the non linear material .
