Essential Reasons to Schedule a Charpy Impact Test

Invented by George Augustine Albert Charpy in the year 1900, the Charpy impact test is still one of the commonly used and employed tests for evaluating the relative strength or thickness of a material. The economic Charpy impact testing procedure is also quite fast and accurate, reasons that increase its popularity. The test uses a standard notched test specimen, which is broken or impacted through an impact load. Impact loading may provide information on stiffness, strain, failure mode, and ductility, among other influences of strain. The test measures the energy absorbed by the specimen to determine its sensitivity and toughness towards impact. The Charpy impact testing methodology can be used for various materials, including concrete, metals, ceramics, composites, and polymers. A standard specimen of a Charpy impact test has a dimension of 55 mm x 10 mm x 10 mm.

 

Essential Reasons for Scheduling a Charpy Impact Test

 

The Charpy impact testing procedure can provide both quantitative and qualitative results that may be required for improving the reliability of a process or material, achieving a standard, and for compliance, among other necessary and fruitful purposes. 

 

The energy required for fracturing a material is determined in the quantitative results of the impact test. The strain rate is studied to know its effect on the fracture. Therefore, the extent to which the material can resist impacts and loads can be easily determined by the test.

 

The qualitative results of the impact test are used for determining a material’s ductility. The materials that break down with shear lips or jagged edges yield a ductile fracture. However, other materials produce a brittle fracture. In most cases, a material does not fully align with any of the sides and may have characteristics of both. Therefore, the impact test reveals the extent to which a material can be brittle or ductile, which may be necessary and required for choosing a given material for a given purpose. 

 

The Charpy not only determines the suitability of materials and their strength but also provides other advantages:

 

  • Evaluation and testing of new products.
  • Testing composites in the most cost-effective way.
  • Determining the impact resilience of crucial structures, including bridges.

 

The Charpy impact test provides fast and measurable results and should be scheduled to improve quality and ensure the reliability of the materials.
