This paper presents an approach to damage identification in beams by modal curvatures based on the use of beamforming algorithms. These processors have been successfully used in acoustics for the last thirty years to solve the inverse problems encoun

Propagating guided waves in a homogeneous, isotropic, prestressed, hyperelastic plate show nonlinear characteristics that depend on the state of initial prestress. These nonlinear phenomena include higher harmonic generation, occurring when Lamb wave

The dynamic nonlinear problem of wave propagation in infinitely long hysteretic beams under bending is addressed. Such a problem is tackled by proposing an asymptotic treatment based on the method of multiple scales. The equations of motion are obtai

The description of the mechanical behavior of composite materials is an open challenge in engineering. The focus of this work is on micro-cracked/micro-porous composites, made of stiff grains embedded in a cracked or porous deformable matrix. Grains

Modal curvatures have been claimed to contain local information on damage and to be less sensitive to environmental variables than natural frequencies. However, simply using the difference between modal curvatures in the undamaged and damaged states

This paper addresses the nondestructive testing of platelike structural components that are widely used in aerospace, marine, and civil structures. The objective is not only to detect and localize possible defects, but to reconstruct a picture of the

This article presents improvements to ultrasonic imaging of solid platelike structures using the minimum-variance distortionless response (MVDR) beamforming processor. The primary application of this work is in the nondestructive testing (NDT) of pla
