Universal testing machine load frames come in single or dual column configurations and are available in force capacities up to 2,000 kN. . Wood and composites are most commonly tested with the 4-point bend test. The 4-point test requires a deflectometer to accurately measure specimen deflection at the center of the support span. Test results . From the presented testing and analysis several comments can be offered. The Weibull moduli obtained from the 4-point bending tests are generally lower than from the 3-point bending tests. This could be because the 4-point bending test subjects a larger volume of the specimen to tension compared to the 3-point bending test.TestResources is a manufacturer & provider tensile, compression, bend, fatigue testing machines and equipment for testing different materials and products. .
