What is ASTM C393?
ASTM C393 is a test method designed to determine the core shear properties of sandwich constructions. The shear properties are determined via a bend test in a 3- or 4-point loading condition.
What is astm D1388?
ASTM D1388 – 18 Standard Test Method for Stiffness of Fabrics.
Why flexural test is done?
The most common purpose of a flexure test is to measure flexural strength and flexural modulus. Flexural strength is defined as the maximum stress at the outermost fiber on either the compression or tension side of the specimen. Flexural modulus is calculated from the slope of the stress vs. strain deflection curve.
What is Gurley stiffness?
Stiffness. The Gurley unit is a measure of the stiffness of a material. Since the measurement device holds a piece of material vertically and tests the force required to deflect the material a given amount.
What is stiffness in textile?
Stiffness is a special property of a fabric. It is the tendency of the fabric to keep standing without any support. It is a key factor to study of handle and drape.
What is flexural stiffness of beam?
The flexural stiffness is a criterion of measuring deformability. The flexural stiffness of a structure is a function based upon two essential properties: the elastic modulus (stress per unit strain) of the material that composes it, and the moment of inertia, a function of the cross-sectional geometry.
What is Taber stiffness?
Taber Stiffness Units are defined as the bending moment of 1/5 of a gram applied to a 1 1/2″ wide specimen at a 5 centimeter test length, flexing it to an angle of 15°. A Stiffness Unit is the equivalent of one gram centimeter.

What is bending stiffness of a fabric?
The bending stiffness of a textile is a feature determining comprehensive indicators such as fabric drapability and handle. Most methods of assessing the bending stiffness of textiles are based on the principle of the determination of the strain and force dependence.
What is bending length in textile?
Hence bending length can also be defined as the falling length, when a fabric falls under its own weight to a specific length, having specific angle. There are many factors which tells the bending length of the fabric. But the most important is one of the fiber parameters called flexural rigidity.
What is bending stiffness of a beam?
From Wikipedia, the free encyclopedia. The bending stiffness ( ) is the resistance of a member against bending deformation. It is a function of the Young’s modulus , the area moment of inertia. of the beam cross-section about the axis of interest, length of the beam and beam boundary condition.
