Acoustic emission accompanying the onset of surface microcracks [PDF]
, 1985 The acoustic emission accompanying the formation and growtb of shallow cracks (microcracks) on the surface of an isotropic solid is investigated. The radiation directivity patterns of two- and threedimensional microcracks are calcuiated for various ...

A stress-based macroscopic approach for microcracks unilateral effect [PDF]
, 2010 The question of the nonlinear response of brittle materials undergoing elastic damage is investigated here. Owing to the specific nature of microcracking, the macroscopic behaviour of these materials is complex, generally anisotropic owing to the ...

Isotropic brittle damage and unilateral effect [PDF]
, 2010 This Note investigates the isotropic version of a general macroscopic model for brittle damage accounting for unilateral effects proposed by Welemane and Cormery (H. Welemane, F.

Correlation between Coda Wave and Stresses in Uni-Axial Compression Concrete
Applied Sciences, 2018 Stresses in structures are usually converted by measured strains based on corresponding constitutive relations of materials. However, it is difficult to determine the constitutive relation of the material accurately, which leads to significant ...

Genipin does not reduce the initiation or propagation of microcracks in collagen networks of cartilage [PDF]
, 2022 OBJECTIVE: We recently initiated microcracks, i.e. micron-scale cracks in the collagen networks of cartilage, using both single low-energy impacts and unconfined, cyclic compressions.

Journal of the Mechanical Behavior of Materials, 2019 Concrete behaves as a brittle material due to its low inherent tensile strength, but it can also exhibit a markedly ductile behavior when coupled with transverse reinforcement like steel stirrups. The role of stirrups is to enhance confinement effect, to
