Physical and mechanical properties basics

Flexural Strength is the capacity of a material to resist deformation under bending moment. It is sometimes called Bending Strength.

Tensile Strength is the capacity of a material to resist tension/stretched tight.

The similarity is that, by definition - They are both mateirl's capacity in resisting deformation under loads. But the loads to which they are resisting are different.

Flexural strength is basically bending strength .The flexural strength of a material is defined as the maximum bending stress that can be applied to that material before it yields. It is also called as bending strength or modulus of rupture.
The flexural strength of a material is defined as its ability to resist deformation under load. For materials that deform significantly but do not break, the load at yield, typically measured at 5% deformation/strain of the outer surface, is reported as the flexural strength or flexural yield strength. In other words, Flexural testing is used to determine the flex or bending properties of a material. Sometimes referred to as a transverse beam test, it involves placing a sample between two points or supports and initiating a load using a third point or with two points which are respectively call 3-Point Bend and 4-Point Bend testing. Maximum stress and strain are calculated on the incremental load applied.

Shore Hardness Scales

* Note: Shore hardness values are relative and approximate, since in practice hardness can be perceived higher or lower than the declared values. Hardness depends on several variables, including dosage of Fine Tuners FT1 and LB1 used, light wavelength and power, exposure time, post-curing settings, time from printing until hardness readings since materials tend to get harder upon time until their properties stabilise in a couple of hours, effect of room temperature when making the hardness readings, specially for flexible grades, etc.

Shore hardness readings also depend on the thickness of the prints. Below 6 mm thickness, and when readings are too close to the sides (less than 12 mm) materials may show lower or higher hardness readings, specially for flexible grades.

Since most 3D prints are usually small in size, perceived hardness (and rigidity) differs from Shore hardness readings undertaken with bigger prints, with more than 6 mm thick and at least 12 mm from the sides.   

Perceived foldability also depends on the thickness of the print: the higher the thickness the lower the foldability for the same resin.
