Force acting on the contact area?

[Rahul Baro]

TL;DR

Hi, I have one doubt actually.
I have a cut section here, two blocks, on the right block you have a pressure of 300 bar acting on it. I want to calculate the force/stress on the contact area between the two blocks. I would request you to help me please.

Material - SS 316

Welcome, Rahul.
You need to calculate the sectional area upon which that pressure is acting.
$F=PA$
You will also need the angle of the surfaces in contact.

I am not sure about the sectional area. what should i consider it as? and how the angle will effect here ? can you please tell

The only numerical value you have provided is a pressure.
But the diagram is a perpendicular section that has no area.
We need more information.

1. Is this a hydraulic seal or maybe part of an assembly process?
2. Is the section cut through part of a rectangular or a circular block?

3. What material is block 1?
4. What are the dimensions of block 1?

5. What material is block 2?
6. What are the dimensions of block 2?
7. What force is applied to block 2?

The diagram does not show all the forces acting on block 1 if it is in equilibrium.

Its a part of an assembly process.
section cut through is a part of a circular block.
Hardness of block 1 is 45 and hardness of block 2 is 35.
the diameter of block 1 is 242mm and diameter of block 2 is 170mm.
the pressure coming on block 2 is 330bar.
block 2 is stationary

The block one is kept stationary and only a pressure of 330 bar is applied on block 2

 

[Baluncore]

The block one is kept stationary and only a pressure of 330 bar is applied on block 2

Then why do you show 300 bar applied to block 1 ?

You give the pressure but not the area.
The pressure multiplied by the area will be a force.
That force will be transferred from block 1 to block 2.
Block 2 must be restrained somehow.
Block 2 cannot float in space.

If the blocks are circular, then please show a full sketch with all dimensions.
