Dog-bone-shaped specimens are widely used for determination of the tensile behavior of UHPC, but there is no standard test method or specimen design for the characterization of tensile behavior. In this study, an evolving strategy on designing a direct tension test (DTT) specimen is first conducted using numerical finite element analysis The ASTM D638 standard is defined as a testing method to determine the tensile strength of both reinforced and non-reinforced plastics. This protocol is performed on dog bone shaped samples and under different pre-treatment, temperature and humidity conditions as per the different speeds of the testing machine
The ASTM D638 test method is one of the most popular methods used to determine the tensile strength of reinforced and unreinforced plastics using a standard dumbbell or dog-bone shaped sample under consistent temperature, humidity and test speed. Materials up to 14 mm thick can be tested using this procedure Tensile Testing of Metal Dogbone Specimens. The tension testing of metallic shouldered end specimens are commonly performed using test methods such as ASTM E8. These machined specimens often come in the form of a Dumbbell, Dogbone, or Button End and use the specialized ends for unique gripping needs during testing Specimens can be die cut, machined, or molded.

'ASTM D638-Standard Test Method for Tensile Properties of Plastics' can be adapted to the testing of TSLs. In order to ensure we get gauge length breaks, as a test lab we instead turn to end tabbing. There seems to be a sense of unnecessary mystery in the composites industry surrounding the end tabbing of composite test specimens. This view is not helped by the following statement in ASTM D3039-17 for tensile testing 
Tensile testing, also known as tension testing, is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum elongation and reduction in area.

The initial sampl The nice part about ASTM D 882 is that the specimens are strips of film that are 1 wide by 6 long and are not dumbbell or dog bone shaped. The flat geometry of the specimens and the typical characteristic of films having high elongation allow most users to avoid using an extensometer which allows them to reduce the cost of the testing. tensile Testing. Tensile testing is used to determine the strength and ductility of a sample while an axial stretching load is applied. These types of tests may be performed under ambient or controlled (heating or cooling) conditions to determine the tensile properties of a material. The MES tensile test lab provides tensile testing on metals. A tensile test is a standardized test used for finding the properties for a specific material. In a tensile test, the sample material is lathed into the shape of a 'dog bone' for comparing the results of other materials. If all of the sample materials had the same shape, it's easier for us to compare the properties of the different materials
