The flexure test method measures behavior of materials subjected to simple beam loading. It is also called a transverse beam test with some materials.Flexural strength is defined as the maximum stress in the outermost fiber.This is calculated at the surface of the specimen on the convex or tension side. Flexural modulus is calculated from the slope of the stress vs. deflection curve.A flexure test produces tensile stress in the convex side of the specimen and compression stress in the concave side. This creates an area of shear stress along the midline. To ensure the primary failure comes from tensile or compression stress the shear stress must be minimized. This is done by controlling the span to depth ratio; the length of the outer span divided by the height (depth) of the specimen.It is essential to determine the flexural strength, resistance to wear and abrasion properties of tiles for effective control.The Flexure Strength Testing Machines are designed to provide maximum rigidity throughout their working range. The load is applied by the downward movement of a hydraulic ram. The jack can be raised or lowered for testing ...
... different size beams. The load is indicated on a calibrated Bourdon tube type load gauge of range : 0-100 kN x 0.5 kN (0-10,000 kgf x 50 kgf). The load gauge is calibrated against NPL/NCCBM certified proving ring.

The compression testing machine series is mainly used for compressive strength test of concrete, cement, brick, stone and other building materials. It can also be used to test the mechanical properties of other materials. It adopts computer and can finish automatic compression test. By connecting printer, it can save and print testing results.It is widely used in all kinds of industries and has many advantages, such as high precision, high reliability, low noise, and easy operation and so on.he Flexure Strength Testing Machines are designed to provide maximum rigidity throughout their working range. The load is applied by the upward movement of a hydraulic ram. The jack can be raised or lowered for testing different size beams. The load is indicated on a calibrated Bourdon tube type Pressure Gauge of range: 0-100kN x 0.5kN (0-10,000 kgf x 50 Kgf). The load gauge is calibrated against NPL/ NCCBM certified proving ring.Flexural strength (stress) is a measure of how much force a test bar can support before breaking and is calculated using a three point bending formula. Flexural stress at 5% strain is a measure of the force required to bend the test bar a certain amount and is used when the test bar bends too far without breaking. Flexural modulus is a measure of stiffness or rigidity and is calculated by dividing the change in stress by the change in strain at the beginning of the test. ASTM D790 flexural properties are useful for calculating how much a plastic component will flex and if it will break when subjected to bending forces.
