👉 Strain math is a branch of mathematics that deals with the study of deformations and distortions of geometric objects, particularly in the context of differential geometry and topology. It quantifies how much a shape can be stretched, compressed, or bent without tearing or gluing it. This is achieved through concepts like the Riemannian metric, which measures distances and angles on curved surfaces, and the curvature tensor, which describes how much a surface deviates from being flat. Strain math is crucial in understanding the behavior of materials under stress, the structure of spacetime in general relativity, and the evolution of shapes in computer graphics and engineering. Essentially, it provides a mathematical framework to analyze and predict how objects change under various forces or transformations.
