four point bending test of wood based composites

flexural properties by four-point bending astm d627

2the major difference between the three point and four point flexural tests is the location of the bending moment. the four point bending method allows for uniform distribution between the two loading noses, whilst the three point bending method’s stress is located under the loading nose.【Get Price】

standard test method for flexural properties of polymer.

procedure a is used for three-point loading and procedure b is used for four-point loading. this test method was developed for optimum use with continuous-fiber-reinforced polymer matrix composites and differs in several respects from other flexure methods, including the use of a standard span-to-thickness ratio of 32:1 versus the 16:1 ratio used by test methods d790 (a plastics-focused method covering three-point flexure) and d6272 (a plastics-focused method covering four-point flexure).【Get Price】
