Mechanical Properties and Testing

Mechanical testing is crucial for evaluating how materials respond to loads, ensuring safety and durability in engineering systems. Various tests, including tensile, compression, and fatigue tests, provide important metrics such as strength, ductility, and toughness. Understanding mechanical properties and their definitions is essential for predicting material behavior under load and ensuring appropriate material selection in engineering applications.
