Stress relaxation small punch testing of P92 steel
Original language description
New application of small punch test (SPT) could be employed as the stress relaxation testing at elevated temperatures. Basically, the specimen has to be loaded at a given deflection rate to a specific central deflection that conforms conditions of the membrane-stretching regime. The deflection of the disc is then held constant and the force relaxes as the elastic strain is replaced with inelastic creep strain. The force vs. time response during relaxation can be recalculated to stress vs. time response,differentiated and divided by elastic modulus to give the creep rate and finally its dependence on the stress.
