Abstract:
An apparatus for testing tensile properties of a sample under dynamic conditions, said apparatus comprising:an elongated housing having a length and a raised portion extending the length of said housing and an upstanding wall spaced parallel from said raised portion, wherein said raised portion and said upstanding wall define a trough; a rail mounted to said housing disposed between said raised portion and said upstanding wall; first and second clamping jaws slidably mounted to said rail, said clamping jaws being formed to grippingly engage the sample; rate measuring sensor means for measuring a rate of sliding of at least one said clamping jaw relative to said rail; distance measuring sensor means for measuring distance between said clamping jaws; load sensor means for measuring tensile load applied to the sample; and a microprocessor operatively connected to the rate measuring sensor means, the distance measuring sensor means and the load sensor means for determining characteristics of sample.
