19) Indicate the incorrect expression for plastic deformation of metallic materials: a) The level of the yield strength does not indicate if necking occurs after a small amount of homogeneous deformation or after a large amount (in other words, if the start of necking is delayed or not). b) Greater strain hardening exponent means an earlier 'necking'. c) If 'n' and 'm' parameters are greater the larger the homogeneous plastic deformation range. d) When plastic deformation progresses sufficiently, the negative contribution to the strain hardening of the metal due to local adiabatic heating starts the local plastic deformation.
