Abstract

Highlights: It is proposed a new macroscopic theoretical approach to study damaged solids. Two types of defects are considered: cracks and round voids. The approach applied is founded upon the Boundary Integral Equations method. A correlation between strength and wave speed of the US impulse is established. Abstract: A new macroscopic theoretical approach is proposed for strength analysis of damaged elastic bodies. Two types of defects are considered: cracks and round voids. The method applied is founded upon the Boundary Integral Equations (BIEs) method. The problem is studied for both anti-plane and in-plane mode of deformation. We give respective diagrams for calculated physical quantities. The results obtained in frames of the BIE method are compared with an alternative technique based on a propagation of ultrasonic impulses through the damaged media. There is evaluated a correlation between strength of the micro-damaged media and the wave speed of the of ultrasonic (US) impulse.
