3 1 the failure probability of a structure ω is function of the two weibull parameters namely the weibull scale.
When does it make sense to test in 3 point compared to 4 point bending.
The highest or maximum bend stress occurs under the loading anvil in three point flexural bend tests.

The four point flexural test provides values for the modulus of elasticity in bending flexural stress flexural strain and the flexural stress strain response of the material.

It produces its peak stress at the material mid point and reduced stress elsewhere.
These bending tests simulate tensile and compression stress on a wood specimen and its physical response behavior is monitored.
Custom orders can be produced in a matter of days.
Using a range of test methods.
3pt and 4pt available in heights from 1 4 to 4.
Heights from 1 4 to 4 in 2pt or 3pt center bevel or side bevel.
Maybe this is an odd question but so far i don t understand why we have two standard methods for testing bending flexural strength of fine ceramic 3 points and 4 points bending tests though.
Bending tests at least a dozen were performed for each reference materials and a distribution of failure stresses σ f was deduced.
In four point bend tests the maximum flexural stress is spread over the section of the beam between loading points.
