Materials vs OMDR — Key differences for NEET MDS
Stress = Force divided by Area = internal resistance. Strain = change in length divided by original length = deformation. Elastic modulus = Youngs modulus = stress divided by strain = stiffness. Toughness = total area under stress-strain curve. Resilience = energy absorbed in elastic region only. Hardness tests: Knoop for micro surfaces, Vickers universal, Brinell for macrosurfaces.

Stevens-Johnson syndrome = severe mucocutaneous EM. Dermatitis herpetiformis = celiac disease associated. Epidermolysis bullosa = genetic blistering = absent collagen VII.
