Mechanical testing is a suite of experimental techniques used to quantify the mechanical properties and deformation behavior of materials, components, or structures under controlled loading conditions. It encompasses methods such as tension, compression, bending, torsion, hardness, impact, fatigue, creep, and fracture toughness tests, performed using calibrated test machines and standardized specimen geometries. Measured responses—typically load, displacement, strain, and time—are analyzed to derive parameters including elastic modulus, yield strength, ultimate strength, ductility, hardness, fatigue life, creep rate, and fracture resistance, providing essential input for material selection, constitutive modeling, design verification, quality control, and failure analysis in engineering and materials research.
Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution is needed for a wide range of applications, from robotics ...
