Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

Last month we acquainted you with a few unique procedures for using conventional tune-up devices—such as a vacuum gauge, timing light and electrical analyzer—for evaluating the efficiency and ...

Defects can occur naturally during composite fabrication, and damage can be induced by impacts in service, but these tend to be relatively uncontrolled events. It was desired to induce an easily ...

The size of designs continues to grow and IC manufacturers are pushing for higher test quality, especially in mission-critical applications such as transportation and medicine. More advanced nodes ...
