Slow Strain-Rate Tensile Testing Machine.

摘要

A slow strain-rate tensile testing machine intended for use in investigations into adhesive-bond durability and hydrogen embrittlement in metals is described. It is of a basically simple design to facilitate ease of manufacture and its stepping motor drive permits electronic control of the straining rate over a range of several orders of magnitude. The driving circuitry provides a high degree of stability in the straining rate over extended periods and the entire system may be adapted to computer control if desired.
