Tensile Properties - Materials Write a short note on tensile strength and compressive strength Answer: Tensile Strength: It is determined by subjecting a rod, wire, or dumbbell-shaped specimen to a tensile loading. Tensile strength is defined, as the maximal stress the structure will withstand before rupture. Due to tensile loading, there is an alteration in the … [Read more...] about Tensile Properties – Materials

Material Hardness – Types, Testing Methods And Units Write a short note on Hardness. Answer: Hardness is defined as resistance to permanent indentation. Initially, an arbitrary hardness indexing scheme known as the Mohs scale is used to determine hardness. It does not have any clinical relevance, though the measurement of hardness is an indicator of other … [Read more...] about Material Hardness – Types, Testing Methods And Units
