Mechanical Testing

Definition

Mechanical testing refers to a series of assessments used to evaluate the mechanical properties of materials and components, including strength, ductility, hardness, and elasticity. This process is crucial in understanding how materials behave under different forces and conditions, which is especially important in additive manufacturing where the properties of materials can vary significantly based on how they are produced. By simulating real-world conditions, mechanical testing helps ensure that biomimetic designs can withstand the demands placed upon them in practical applications.
