Classification of Concrete Crack using Deep Residual

Cracks in Concrete | Types & Causes of Concrete Cracking

Types of cracking. Cracks in concrete can be classified into different types. Main types are discussed briefly in this article. Flexural Cracks: These cracks may occur in reinforced concrete elements after the hardening state. Flexural cracks are vertical cracks that develop at the tension zone of the member up to their neutral axis.

Residual stress - Wikipedia

Residual stresses are stresses that remain in a solid material after the original cause of the stresses has been removed. Residual stress may be desirable or undesirable. For example, laser peening imparts deep beneficial compressive residual stresses into metal components such as turbine engine fan blades, and it is used in toughened glass to allow for large, thin, crack- and scratch

Detection of Surface Cracks in Concrete Structures using

Detection of surface cracks is an important task in monitoring the structural health of concrete structures. If cracks develop and continue to propogate, they reduce the effective load bearning surface area and can over time cause failure of the structure. The manual process of crack detection is painstakingly time-consuming and suffers from

Flexural Behaviors of ECC and Concrete/ECC Composite Beams

For ECC/concrete composite beams, strategic application of ECC can lead to considerable increase of energy dissipation capacity. When a layer of ECC is placed in the tension zone, the crack width along the beam can be well controlled. High residual strength and stiffness of the composite beam can hence be obtained.
