Shown as formula 1, the essential condition of VSR is that the sum of dynamic stress and residual stress must be greater than yield limit of material.
From VSR theory, the sum of dynamic stress and residual stress must be greater than yield limit of material and less than fatigue limit of material.

Introduction Due to its strength and durability, concrete is one of the most widely used building materials worldwide, and the performance of concrete structures has benefited from fiber reinforcement because fibers provide control over crack development and propagation [1].
Materials and Methods a.
Fiber characteristics The fibers used in concrete, whether steel or synthetic, provide reinforcement to the material, improve its tensile strength, and control cracking.

Introduction Wood-plastic composites (WPCs) are composite materials made of wood fiber/flour and plastic.
In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.
Beside the amount of additive, since the hardness is the surface property rather than bulk property of the materials.
