ASTM D790: Standard test methods for flexural properties of unreinforced and reinforced plastics and electrical insulating materials. ASTM E1290: Standard Test Method for Crack-Tip Opening Displacement (CTOD) Fracture Toughness Measurement. ASTM D7264: Standard Test Method for Flexural Properties of Polymer Matrix Composite Materials.
It is determined from the slope of a stress-strain curve produced by a flexural test (such as the ASTM D790), and uses units of force per area. [2] The flexural modulus defined using the 2-point (cantilever) and 3-point bend tests assumes a linear stress strain response. [3] Flexural modulus measurement
Tensile testing on a coir composite. Specimen size is not to standard (Instron). Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure.
The flexural strength is stress at failure in bending. It is equal to or slightly larger than the failure stress in tension. Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test.

ASTM C1161: Standard Test Method for Flexural Strength of Advanced Ceramics at Ambient Temperature; ASTM D6272: Standard Test Method for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials by Four-Point Bending; ASTM C393: Standard Test Method for Core Shear Properties of Sandwich Constructions by ...
ASTM standard covering resistance curve suggests using Irwin's method is acceptable for small plastic zone and recommends using Secant method when crack-tip plasticity is more prominent. Also since the ASTM E 561 standard does not contain requirements on the specimen size or maximum allowable crack extension, thus the size independence of the ...
ASTM D5617 – 04(2015) – Standard Test Method for Multi-Axial Tension Test for Geosynthetics. DIN EN 17117 – A German standard describes methods of the test using biaxial stress states for the determination of the tensile stiffness properties of biaxially oriented coated fabrics
