Since it is almost impossible to carry out a comprehensive parametric investigation
experimentally for internal cracks with different geometry and orientation, a good numerical …

This work presents a nonlocal theory based on ordinary state-based (OSB) peridynamics for
numerical modeling of crack propagation under loadings and peri‑ultrasound modeling for …

A newly developed nonlinear ultrasonic (NLU) technique called sideband band peak count-
index (or SPC-I) measures the degree of nonlinearity in materials by counting the sideband …

Welding is a commonly used method for joining two or more parts together in steel
construction. Various defects in weld regions such as cracks, pores, and slag inclusion can …

Peridynamics is widely adopted for understanding the propagation of damage in materials,
however, peridynamics modeling of guided wave propagation in materials is still at its …

In this paper, the crack propagation and failure behavior of Ni/Ni 3 Al bi-material structure
are investigated under the framework of peridynamics (PD). The effects of the location of the …

Propagating guided waves in a homogeneous, isotropic, prestressed, hyperelastic plate
show nonlinear characteristics that depend on the state of initial prestress. These nonlinear …

Ductile metallic materials such as aluminum alloy, brass and steel are widely used in
engineering structures. Monitoring elastoplastic deformation in these materials is important …

Some topographies in plate structures can hide cracks and make it difficult to monitor
damage growth. This is because topographical features convert homogeneous structures to …

Peri-ultrasound modeling which is based on nonlocal peridynamics is found and proven to
be effective for modeling nonlinear waves propagating and interacting with damages in …
