Abstract
A new experimental method has been developed that provides a quantitative description of the evolution of damage indicators under cyclic loading of composite samples with stress concentrators. Damage parameters are defined as the deformation response to the application of an artificial cut of a given length, which extends from the contour of the central through hole in a flat rectangular sample under constant external load. Based on the test results of eight samples, the current values of damage indicators at various stages of fatigue loading were obtained. These data reveal the dependence of the required parameters on the number of loading cycles. On this basis, a damage accumulation function was constructed for the considered range of cycles. It has been established that this function refers to the first stage of the process under study. The results obtained are a necessary basis for planning further experiments.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
