Structural Health Monitoring of Thin Shell Structures

International Journal of Mechanical System Dynamics, Volume 5, Issue 1, Page 20-39, March 2025.
ABSTRACT Thin plate and shell structures are extensively used in aerospace, naval, and energy sectors due to their lightweight and efficient load‐bearing properties. Structural Health Monitoring (SHM) implementations are becoming increasingly important in these industries to reduce maintenance costs, improve reliability, and ensure safe operations ...

Using the inverse finite‐element method to harmonise classical modal analysis with fibre‐optic strain data for robust population‐based structural health monitoring

Strain, Volume 61, Issue 1, February 2025.
Abstract Vibration‐based approaches to structural health monitoring (SHM) gained increasing significance for assessing the behaviour of existing structures because of their non‐intrusive nature and high sensitivity to damage. However, data availability often limits the application of SHM approaches.

Retrieval of the optical soliton solutions of the perturbed Schrödinger–Hirota equation with generalized anti‐cubic law nonlinearity having the spatio‐temporal dispersion

Mathematical Methods in the Applied Sciences, Volume 48, Issue 2, Page 2164-2178, 30 January 2025.
In this study, we obtained optical soliton solutions of the perturbed nonlinear Schrödinger–Hirota equation with generalized anti‐cubic law nonlinearity in the presence of spatio‐temporal dispersion. This equation models the propagation of optical pulses in fiber optic cables.

Regional Stiffness and Hardening Indices: New Indicators Derived from Multidimensional Dynamic CTA for Aneurysm Risk Assessment

Advanced Science, Volume 11, Issue 47, December 18, 2024.
Two new indicators are derived from nonlinear stress–strain behavior obtained through in vivo biomechanical analysis of patient‐specific multidimensional dynamic computed tomography angiography. The regional stiffness index indicates the average stiffness while the hardening index reflects the pace of strain hardening.
