Advanced Materials Testing

One Eighty is SANAS and ISO accredited for materials testing and has the most widely scoped materials testing laboratory in Africa

What are Advanced Materials?
Advanced Materials are materials with engineered properties created through the development of specialised processing and synthesis technology. They include plastics, polymers, ceramics, glass, composites, adhesives, lubricants, refrigerants, building materials, paints & coatings, industrial chemicals, biomaterials,
wood-based materials and electronic materials.

Energy absorption A process that takes place as a result of several different mechanisms such as matrix yielding and cracking, fibre debonding and breakage, delamination, splaying and fragmentation of the multilayer laminate
Lateral expansion A measure of the ductility of the specimen. When a ductile metal is broken, the test-piece deforms before breaking, and material is squeezed out on the sides of the compression face. The amount by which the specimen deforms in this way is measured and expressed as millimetres of lateral expansion.
Shear fracture A type of failure that occurs when a force is applied parallel to the cross-section of a material. Shear fracture percentage is, therefore, a parameter used to quantify the amount of ductile shear fracture a material experiences at the fracture surface. The shear fracture percentage area is one of the key measurements made during a Charpy impact test.
Fusion strength strength of a sample after merging of different elements.
Tensile strength The resistance of a material to breaking under tension.
Yield strength Yield strength is the maximum stress that can be applied before a sample begins to change shape permanently. This approximates the elastic limit of a sample. If stress is added to the sample but does not reach the yield point, it will return to its original shape after the stress is removed.
Yield point elongation In materials that exhibit a yield point, the Yield Point Elongation (YPE) is the difference between the elongation of the sample at the start and at the finish of discontinuous yielding (the area in which an increase in strain occurs without an increase in stress).
0.2% Proof stress The 0.2% offset yield strength (0.2% OYS, 0.2% proof stress, RP0. 2, RP0,2) is defined as the amount of stress that will result in a plastic strain of 0.2%.
0.5% Proof stress In some cases, particularly with low strength rod or wire, it is difficult to accurately measure the plastic strain. In this case, the total strain is measured, and the 0.5% extension under load yield strength (0.5% EUL, RT0.5) is listed instead.
Modulus of elasticity An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance’s resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. It is the ratio of stress, below the proportional limit, to the corresponding strain. In terms of the stress-strain curve, the modulus of elasticity is the slope of the stress-strain curve in the range of linear proportionality of stress to strain.
Elongation Elongation is defined as the length at breaking point expressed as a percentage of its original length (i.e. length at rest).
Area reduction The reduction of area is reported as additional information (to the percent elongation) on the deformational characteristics of the material. The two are used as indicators of ductility, the ability of a material to be elongated in tension. It is the difference between original cross-sectional area of a specimen and the area of its smallest cross section after testing.
Vickers hardness Hardness of materials in the micro hardness test load range. In general, an indenter is pressed into the surface of the material to be tested under a specific load for a definite time interval, and a measurement is made of the size or depth of the indentation.
Portable hardness In-situ hardness of materials in the micro hardness test load range.
Microstructure The fine structure of a material as revealed by microscopy.
Ferrite A ceramic compound consisting of a mixed oxide of iron and one or more other metals.
Fillet weld Fillet welding refers to the process of joining two pieces of metal together when they are perpendicular or at an angle.
Corrosion Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, carbonate or sulfide.
Pitting Pitting corrosion, or pitting, is a form of extremely localized corrosion that leads to the creation of small holes in the metal.
