Document Summary

Bcc: a = (cid:2781) (cid:2780) n = number of atoms associated with each unit cell. Chapter 6- mechanical properties of metals (cid:1848)(cid:3030) = volume of the unit cell. Linear density (ld) = (cid:3041)(cid:3048)(cid:3040)(cid:3029)(cid:3032)(cid:3045) (cid:3042)(cid:3033) (cid:3028)(cid:3047)(cid:3042)(cid:3040)(cid:3046) (cid:3030)(cid:3032)(cid:3041)(cid:3047)(cid:3032)(cid:3045)(cid:3032)(cid:3031) (cid:3042)(cid:3041) (cid:3031)(cid:3045)(cid:3032)(cid:3030)(cid:3047)(cid:3042)(cid:3041) (cid:3049)(cid:3032)(cid:3030)(cid:3047)(cid:3042)(cid:3045) (cid:3039)(cid:3032)(cid:3041)(cid:3034)(cid:3047) (cid:3042)(cid:3033) (cid:3031)(cid:3045)(cid:3032)(cid:3030)(cid:3047)(cid:3042)(cid:3041) (cid:3049)(cid:3032)(cid:3030)(cid:3047)(cid:3042)(cid:3045) Engineering strain: = (cid:2777)(cid:2777) = (cid:2777) Where (cid:2777) = original length before any load is applied. Poisso(cid:374)"s ratio: v = - (cid:3299) (cid:3301) = - (cid:3300) (cid:3301) Hall-petch equation (yield strength): (cid:3052) = (cid:2868) + (cid:1863)(cid:3052)(cid:1856) (cid:2869)(cid:2870) %of cold work: %cw = ( 0 0. Where e = modulus of elasticity, (cid:2201) is specific surface energy and a is one-half the length of an internal crack. Thermal expansion: the magnitude of a thermal stress developed by a temperature t is dependent on the coefficient of thermal expansion (cid:3039) and the modulus of elasticity e: = e t. Stead-state creep: (cid:2202) = (cid:2778) , where k and n are constants.
