What is Resilience and Modulus of Resilience?

October 22, 2016July 11, 2015 by Anand Paul

Resilience and Modulus of Resilience Resilience. Resilience is the total elastic strain energy which can be stored in the given volume of metal and can be released after unloading. it is also equal to area under load deflection curve within elastic limit. Modulus of Resilience is defined as elastic strain energy per unit volume and … Read more What is Resilience and Modulus of Resilience?

What is Proof Stress?

August 3, 2015July 9, 2015 by Anand Paul

Proof Stress In some ductile materials such as Aluminium, Copper, Mild Steel, the yield point cannot be clearly defined during tension test, therefore yield stress is Unknown. For such metals design stress called PROOF stress is calculated using offset method. An offset of strain equal to given permissible plastic strain, eg at 0.2% for Al, … Read more What is Proof Stress?
