In impact testing of materials, the notches are made to reduce the stress concentration.(a) True(b) FalseThis question was addressed to me in an internship interview.Query is from Destructive Testing in division Inspection Testing in Foundries of Casting-Forming-Welding I

Answer»

Right answer is (b) False

The BEST I can EXPLAIN: In IMPACT testing of materials, the notches in specimen are made intentionally to INCREASE the stress concentration so as to increase the tendency to fracture as most of the mechanical components have stress raisers. The notch material should be tough enough to WITHSTAND the impact force.
