Microfibers—the tiny fibers that break loose from textiles—might be small, but they add up to a significant environmental concern. A University of Plymouth study found that up to 700,000 microfibers ...

The damage of road base course has the characteristics of strong concealment and difficulty in detecting. For this reason, the impact imaging method has been used for detection of road base course.

Measuring how materials respond to different deformation speeds is imperfect, leaving gaps and uncertainties across strain rates. A single, self-consistent method to measure hardness across 11 orders ...

An experimental investigation of circular concrete-filled steel tubular (CFST) columns subjected to very low-elevation lateral impacts was performed. Six circular CFST members were prepared for ...

While performing notch impact tests, a material specimen is tested under impact loading in the form of an elongated building block - single-sided, notched and typically tempered. The unnotched rear ...

Southwest Research Institute (SwRI) has expanded and advanced a ballistic resistance testing technique, the Laser-Induced Particle Impact Test (LIPIT), previously limited to using microscopic ...

University of Massachusetts Amherst researchers have discovered a new way to detect per- and polyfluoroalkyl substances (PFAS) in water. This marks an important step forward in creating testing ...
