I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...

In my previous column, I noted that the shear strength and shear stiffness of the core material in a sandwich panel can be determined in situ while performing flexural tests to evaluate other sandwich ...

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 ...
