*Strength and stiffness are not the same thing. Here's an analogy: A rubber band is stretched to failure. The rubber band failed at five pounds of force, but it stretched more than double its length before failure. The rubber band was not v...

Yes there is. If you want a formula you will probably need to ask in physics.

The PVA cryogel will not break. You will need a sharp scalpel to cut it. It is almost like latex rubber in strength. However, you must keep it in water to prevent it from drying out.

ETABS considers the deck as an isotropic material. Isotropic behavior is usually assumed for steel and concrete, although that is not always the case. The behavior of an isotropic material is independent of the direction of loading. In addi...

It is all based upon molecular density. Obviously some materials balance and therefore "mix" well and some don't. The idea is to get the most density from a stable balance. The periodic table of elements will list densities. Carbo...

there are many other materials stiffer than concrete. concrete happens to be a building material because it has a good strength to cost ratio, compared to steel, for instance, but it is a lot heavier for the same strength as steel and concr...

Concrete is basically an artificial rock. It is strong in compression but weak in tension. In reinforced concrete, the purpose of the reinforcement is to provide tensile strength, otherwise the material just cracks where tension is applied ...
