Tensile test determines the strength of the material subjected to a simple stretching operation. Typically, standard dimension test samples are pulled slowly (static loading) and at uniform rate in a testing machine while the strain ( the elongation of the sample) is defined as: Engineering Strain = E = (change in length)/ (original length) = E ...

For transverse cracks, the following limits should be used: • Cracks with a length of <50 mm and width <5 mm are normally acceptable. • Cracks with a length of 50-200 mm should be limited to two per anode face or four per anode. • Cracks with a length >200 mm or those that are >5 mm in width are not acceptable.

An optical method, involving a pyramid-shaped rhombic indenter (longitudinal edge angle 172.5°, transverse edge angle 130°) is pressed into a specimen with a defined test load (between 1 gf and 2 kgf). The larger the indent left by the indenter at a defined test force in the surface of a specimen, the softer the tested material.

Standard. ASTM D638. ASTM D638 is performed by applying a tensile force to a sample specimen and measuring various properties of the specimen under stress. It is conducted on a universal testing machine (also called a tensile testing machine) at tensile rates ranging from 1 to 500 mm/min until the specimen fails (yields or breaks).

What is Transverse strain or lateral strain? The transverse strain is the ratio of change in diameter to the actual diameter of a circular object. For example, if the actual diameter is D and the amount of change in diameter is Δ D, then the transverse strain is (ΔD/D) Transverse stain= (ΔD/D) What is linear strain or axial strain?

A transverse wave is a wave that oscillates perpendicular to the direction of its propagation. Examples of transverse waves include a plucked guitar string, waves in water, the motion created by waving a string, and light. A transverse wave is contrasted with a longitudinal wave— a wave that oscillates in the same direction as its propagation.

Reflection of Transverse Waves. The way in which a transverse wave reflects depends on whether it is fixed at both ends. First, let us discuss a case where the waves are fixed at both ends. The image below shows a transverse wave that is reflected from a fixed end. When a transverse wave meets a fixed end, the wave is reflected but inverted.
