Flexure Testing machine comprises three and
four point bending testing that in response of the material provides values
for modulus of elasticity in
- Flexural stress
- Flexural strain
- Flexural stress-strain
The main advantage of the test comprises ease of specimen
preparation as well as in conducting related testing procedures. The test
method helps in measuring behavior of materials that is subjected to simple
beam loading where maximum fiber stress as well as maximum strain is
calculated for increments of load.
With achieved results plotted in stress-strain diagram, flexural strength
here is defined as maximum stress in outermost fiber and is calculated at
surface of specimen on convex/tension side from slope of stress vs.
deflection curve. The testing is generally done on relatively flexible
materials including polymers and composites.
