Strain research is a field that focuses on understanding the mechanical behavior of materials when subjected to external forces. This research involves studying how materials deform, break, or change shape in response to stress and strain. Researchers in this area typically investigate the relationship between the applied load, deformation, and material properties to develop models and methods for predicting the behavior of different materials under varying conditions. Strain research has applications in a wide range of industries, including engineering, materials science, and biomechanics.
