Introduction

What is Mechanical Testing?

Mechanical testing services are essential in characterizing materials and parts for their mechanical performance characteristics under different environmental conditions. Considering their application domain, these tests define the strength, endurance, and general functionality of the materials used.

Significance of Mechanical Testing

A mechanical test measures the material’s structural limits before failure when subjected to static or dynamic forces. Further, mechanical testing services are vital in raw material selection, determining the effects of heat and other treatments, validating FEA models for engineering components, quality control, and failure analysis and prevention.

Samples Applicable for Mechanical Testing

Our labs employ mechanical testing methodologies to characterize various materials, from metals, composite materials, and electronic components to biological tissues and nanomaterials.
Furthermore, our laboratory offers product-specific testing programs. Also, equipment for characterizing polymers and other specialty samples, such as bio and nanomaterials. Examples include dynamic mechanical analysis (DMA), thermomechanical analysis (TMA), and nanoindentation tests.
