President, Wyoming Test Fixtures Inc. Although less commonly measured than the in-plane tensile properties of a unidirectional (UD) composite, interlaminar tensile strength is an important material ...

One material property that is widely used and recognized is the strength of a material. But what does the word "strength" mean? "Strength" can have many meanings, so let us take a closer look at what ...

Reinforcing steel and ribbed reinforcement bars (rebars) are essential to civil engineering, forming a category of key structural materials which, in the case of concrete-reinforcing steel, are ...

When we think of tensile specimen grips, our first mental image is probably that of the wedge grips that apply uniform clamping forces to the ends of flat test specimens. These were discussed in ...

Not all damage to a load-bearing structure is immediately apparent. So how do civil engineers find out that a bridge or a large hall is no longer safe? Many clues form a picture. Concrete structures ...

Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...
