Fracture mechanics is a field of study that deals with the behavior of materials when subjected to mechanical loading, leading to the formation of cracks and ultimately, failure. This area of research focuses on understanding the factors that influence the growth and propagation of cracks in materials, as well as the conditions under which fractures occur. Fracture mechanics plays a crucial role in a variety of industries, including aerospace, automotive, and civil engineering, as it helps engineers design structures and materials that can withstand mechanical stresses and prevent catastrophic failures.
