Solid mechanics

Solid mechanics is the branch of physics that studies how solid materials deform, bend, and break when forces like pushing, pulling, or twisting are applied to them. It helps engineers and scientists understand everything from why bridges can safely hold weight to how bones fracture under stress, by analyzing the internal stresses and strains that develop within materials. This field is essential for designing everything we rely on, from buildings and airplanes to smartphones and medical implants.
