Transverse rupture strength (TRS) also known as “modulus of rupture”, “bend strength”, or “flexural strength”. It’s a material property, defined as the stress in a material just before it breaks. This can be calculated with the Three Pin Fixture, used with a Hydraulic Press, to exert heavy pressure on a Sintered Test Piece.
1. A Rectangular Green Compact the Metal Powder to be tested is made using a Hydraulic Press with Floating type Die (with upper and lower punch) with fixture for formation of a Standard Rectangular compact.
2. The Green Compact is then Sintered at the required temperature, based on the Metal Powder used for formation of the Compact.
3. The test specimen’s dimensions and density are determined. The load necessary to fracture the Compact Specimen is determined by applying a uniformly increasing force by Hydraulic Press.
4. Transverse Rupture strength (TRS) of the material under test is determined by calculation using the equations, after getting the load on which it broke.
