Testing Machines 

Similar to "Testing Equipment," this refers to mechanical or electromechanical devices designed to apply forces, deformations, or other physical stresses to a specimen or product to determine its properties or performance limits.

Types of Testing Machines  

Universal Testing Machines (UTM): Perform tensile, compression, shear, and bend tests.

Hardness Testers: Rockwell, Brinell, Vickers, Shore.

Impact Testers: Izod, Charpy.

Fatigue Testing Machines: Apply cyclic loads to determine fatigue life.

Creep Testing Machines: Measure deformation under sustained load at elevated temperatures.

Abrasion Testing Machines: Assess wear resistance.

Torsion Testing Machines: Measure resistance to twisting.

Applications in Various Industries: 

Metallurgy: Characterizing metals and alloys.

Plastics & Polymers: Evaluating mechanical properties, optimizing formulations.

Textiles: Strength, elongation, tear resistance testing.

Building Materials: Testing concrete, wood, composites.

Automotive: Component strength and durability.

Technology: 

Servo-hydraulic or servo-electric drive systems, high-precision load cells and extensometers, sophisticated software for test control and data acquisition, closed-loop control, automated specimen handling.

Material Selection Considerations: 

  • Load Frames: High-strength, rigid steel to prevent deflection under load.
  • Grips/Fixtures: Hardened steel, often with specialized coatings or inserts for specific materials.
  • Load Cells: High-grade steel (e.g., stainless steel) with strain gauges.
  • Crossheads/Actuators: Precision-machined steel or aluminum.
