Fracture Mechanics (กลศาสตร์การแตกหัก) Hard Skill
Fracture Mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials and the conditions under which materials fail due to fracture.

Basic
1. Understand fundamental concepts of stress, strain, and basic crack behavior.
2. Can identify types of cracks and simple fracture modes.
3. Familiar with basic terminology related to fracture mechanics.
Level 2
Intermediate
1. Analyze crack propagation using linear elastic fracture mechanics (LEFM) principles.
2. Apply stress intensity factors and energy release rates to assess fracture behavior.
3. Evaluate material toughness and predict failure under different loading conditions.
Level 3
