President, Wyoming Test Fixtures Inc. Unlike metals and plastics, for which tensile and compressive properties are the same or very similar, unidirectional composites exhibit significantly different ...
The in-plane strength properties of a composite material, axial and transverse tension and compression and in-plane shear, are usually the first to be considered in design. However, ...
Engineering thermoplastics vary in their tensile strength. The method for testing the tensile strength of plastics is the same as that of metal; using a “Dog-Bone” test specimen, and recording the ...
Stress is defined as the force per unit area. Thus, the formula for calculating stress is: Where σ denotes stress, F is load and A is the cross sectional area. The most commonly used units for stress ...
Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...
In this article, we will examine three essential aspects of flat tensile specimens: where and why they are used, how ...

Researchers make breakthrough that could transform future buildings: 'Highest compressive strength'
New methods and materials are urgently needed. Researchers make breakthrough that could transform future buildings: 'Highest ...
Extensive laboratory testing and data analyses reveal that the oil and gas industry can reliably estimate foamed-cement sample compressive strength, if the design engineer knows the compressive ...
