The analysis of ultrasonic NDE data has traditionally been addressed by a trained operator
manually interpreting data with the support of rudimentary automation tools. Recently, many …

This paper proposes a new damage index named degree of health (DoH) to efficiently tackle
structural damage monitoring in real-time. As a key contribution, the proposed index relies …

Estimating deterministic single-valued damage parameters when evaluating the actual
health state of a material has a limited meaning if one considers not only the existence of …

Concrete is the main material in building. Since its poor structural integrity may cause
accidents, it is significant to detect defects in concrete. However, it is a challenging topic as …

Functional grading is a distinctive feature adopted by nature to improve the transition
between tissues that present a strong mismatch in mechanical properties, a relevant …

Multi-material additive manufacturing is receiving increasing attention in the field of
acoustics, in particular towards the design of micro-architectured periodic media used to …

This article presents a comprehensive experimental study of impact damage detection for
carbon fiber-reinforced polymer (CFRP) composites using an electromagnetic (EM) sensor …

Compared with body waves, ultrasonic guided waves can provide more local characteristic
information about the interface in the defect detection of adhesive structures. In the paper …

Low-velocity impact damages in composite material laminates, such as matrix cracks,
delaminations and fibre breakage, usually develop inside the material and can be difficult to …

This paper addresses damage evolution in composite materials by using acoustic emission
(AE) as a non-destructive testing method to evaluate residual strength of specimens. Two …
