摘要： A unitary test piece which dimensionally conforms with standardized dynamic tear testing guidelines comprises a middle section and two end sections welded thereto. The middle section is made of the test-subject metallic material. The two end sections are each made of a metallic material which is compatible with the test-subject metallic material, and primarily serve the purpose of combining with the middle section at its longitudinal ends in order to together form the dimensionally suitable test piece. The length of the middle section is at least the minimum such length that will totally encompass plastic deformation of such metallic material when subjected to dynamic tear testing, this depending on the nature of such metallic material. Ferrous end sections are compatible with a ferrous middle section; non-ferrous end sections of a particular designation are compatible with a non-ferrous middle section of the same designation. The invention advantageously permits economical utilization of test-subject metallic material under circumstances in which available samples thereof are expensive, limited, inappropriately or problematically sized, inappropriately or problematically configured, and/or intended to be tested for one or more properties in addition to dynamic tear.
