Fracture mechanics is a branch of materials science and mechanical engineering that focuses on understanding and predicting the behavior of materials when subjected to mechanical loads, which can lead to the initiation and propagation of cracks or fractures. This field is crucial for ensuring the safety and integrity of various structures and components, ranging from aircraft to pipelines and bridges.

Stress analysis involves studying how forces and stresses distribute within a material, identifying regions of high stress concentration that can lead to crack initiation.

This subtopic focuses on the study of how cracks propagate over time under cyclic loading conditions, which is essential for predicting the life span of materials and structures.

Investigating the behavior of brittle materials and understanding the conditions under which they suddenly fracture, such as in the case of glass or ceramics.

Fracture toughness is a material property that quantifies its resistance to crack growth. Research in this area aims to develop methods for measuring and improving fracture toughness in materials.

Examining how environmental factors, such as temperature, humidity, and corrosive substances, can influence the rate of crack growth and material degradation, leading to failure.
