Flexural Strength Testing Machine, The flexural Strength Testing Machine is designed in such a way as to test the flexural strength of concrete beams. These are designed to provide maximum rigidity throughout their working range. The load is applied by the downward movement of the piston that is provided for testing different sizes of beams. These are typically universal testing fracture strength and resistance to fracture. These tests tend to be associated with ductile metals and metal products. Flexural Strength Testing Machine has the ability of unreinforced concrete beams to withstand failure in bending
