Abstract
Two unique measurement systems for generating toughness parameters will be detailed during this presentation. The first is an ACPD Crack measurement system which has been integrated into an instrumented impact test system. This system can be utilized to generate dynamic J-resistance curve information. The second system is a specialized differential extensometer which can be used to accurately measure axial strain in tension specimens experiencing plastic necking. This system can be used for experimentally generating the data necessary for conducting a strain energy density analysis of a material system. This device may alternatively be used to characterize the partitioning of strain across a weldment in uniaxial tension.
