Dynamic load testing is a high strain dynamic test which can be applied after pile installation for concrete piles. For steel or timber piles, dynamic load testing can be done during installation or after installation. The procedure is standardized by ASTM D4945-00 Standard Test Method for High Strain Dynamic Testing of Piles.
The Statnamic load test is a type of test for assessing the load-carrying capacity of deep foundations which is faster and less expensive than the static load test.The Statnamic test was conceived in 1985, with the first prototype tests carried out in 1988 through collaboration between Berminghammer Foundation Equipment of Canada and TNO Building Research of the Netherlands.

The stress intensity factor at the crack tip of a compact tension specimen is [4] = [() / / + / / + /] where is the applied load, is the thickness of the specimen, is the crack length, and is the effective width of the specimen being the distance between the centreline of the holes and the backface of the coupon.
The specimen is then loaded monotonically. A plot of the load versus the crack opening displacement is used to determine the load at which the crack starts growing. This load is substituted into the above formula to find the fracture toughness . The ASTM D5045-14 [4] and E1290-08 [5] Standards suggests the relation
The ASTM standard E1820 for the measurement of fracture toughness [11] recommends three coupon types for fracture toughness testing, the single-edge bending coupon [SE(B)], the compact tension coupon [C(T)] and the disk-shaped compact tension coupon [DC(T)]. Each specimen configuration is characterized by three dimensions, namely the crack ...
Rising Step Load Testing (or RSL testing) is a testing system that can apply loads in tension or bending to evaluate hydrogen-induced cracking (also called hydrogen embrittlement). It was specifically designed to conduct the accelerated ASTM F1624 [ 1 ] step-modified, slow strain rate tests on a variety of test coupons or structural components.
