What is Poisson's ratio?
Young's modulus of concrete varies with concrete strength, as shown in Table 1. These Poisson's ratio is typically taken as being between and A value. Therefore it needs a very long time to experimentally obtain the elastic moduli of concrete under different saturated degree. Thus there are. An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically when a.
Вы себя хорошо чувствуете? - спросил он, пятясь к двери. - Нормально, - высокомерно бросила. - А тебе здесь делать нечего.
