A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

A Standard Test Method is a conclusive procedure that yields a test result. So as to achieve accurate and relevant test results, a standard test method is definite, unambiguous, and experimentally ...

Harnessing the power of machine learning, scientists have developed a material testing technique that improves the accuracy of a previous technique used in manufacturing. Nano-indentation is a process ...

Compared to metals such as aluminum and steel, the number of stiffness and strength properties associated with polymer matrix composites (PMCs) is extensive. For metals, these mechanical properties ...

President, Wyoming Test Fixtures Inc. In addition to providing increased strength properties, fiber-reinforced CMCs exhibit markedly improved toughness and damage tolerance compared to traditional ...

Nondestructive testing is a multidisciplinary profession that blends quality assurance and materials science. Many industries rely upon it, but few uses are more important than in the nuclear power ...

A bullet piercing the protective armor of a first responder, a jellyfish stinging a swimmer, micrometeorites striking a satellite: High-speed projectiles that puncture materials show up in many forms.
