摘要： A shock testing apparatus includes a tower extending upward from a base. The tower includes a guide extending down the tower. A strike plate assembly includes a strike plate positioned below the guide for receiving mechanical shock from a striker striking out from the guide. A tri-axial accelerometer is mounted to the strike plate for data acquisition of three-dimensional shock wave acceleration data. A method of mechanical shock testing components includes dropping a striker onto a strike plate on which is mounted a unit under test (UUT) to generate three-dimensional shock waves through the strike plate. The method includes acquiring data indicative of acceleration in three orthogonal directions in at least one of the strike plate or UUT for a single drop of the striker.

摘要： A method includes preparing a rocklike core sample for compressive testing, the rocklike core sample defining a longitudinal axis and having first and second axial ends. Preparing the rocklike core sample includes providing a throughhole in the rocklike core sample, the throughhole extending between a first opening at the first axial end and a second opening at the second axial end, wherein the first opening and the second opening are dimensioned differently. The rocklike core sample is mounted in a compressive testing apparatus, and a compressive test is performed on the rocklike core sample in the compressive testing apparatus. The compressive test includes compression in axial and radial directions. A related system includes a compressive testing apparatus and a sample preparation apparatus which prepares a rocklike core sample for compressive testing in the compressive testing apparatus, via providing a throughhole in the rocklike core sample.
