文摘
- •
The study investigates deformation of contact faces in the metal-to-metal seal.
- •
The pressure relief valve geometry is simplified to an axisymmetric problem.
- •
Monotonic and cyclic plasticity are considered for AISI type 316N(L) steel model.
- •
The valve lift is caused by fluid pressure penetration used in non-linear FEA.
- •
Fluid pressure distribution over the valve seat is predicted before the valve lift.
