Tension/Compression Fatigue Cracking Grips

Abstract
A pair of grips holding a specimen which includes a pair of through openings for receiving tension pins and a pair of spaced apart, parallel edges. Each of the grips includes a pin, a Davis adjustable key, and a housing. The Davis adjustable key includes a key housing, a movable key portion and a mechanism to move the key portion relative to the key housing. The housing includes a bore for receiving the Davis adjustable key, a bore for receiving the pin, and a slot for receiving that portion of the specimen which includes the through opening and the edge. The Davis adjustable key bore and said pin bore are substantially parallel to each other. The slot is substantially perpendicular to and completely bisecting the pin bore. The slot also partially intersects the Davis adjustable key bore to, when the specimen is received in the slot, the pin received in the through opening and the in bore, and the Davis adjustable key is received in the Davis adjustable key bore, permit the moveable key portion to be moved into engagement with the edge.
