Real-Time Structural Health Monitoring of Concrete Using the Non-Linear Ultrasonic SPC-I Technique

Autor: Umar Amjad, Hamad Alnuaimi, Arash Nikvar-Hassani, Imraan Bokhari, Lianyang Zhang, Tribikram Kundu

Publikováno v: 2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation.

Continuous monitoring is the most desirable approach for ensuring the health/integrity of concrete structures. It is particularly difficult to monitor concrete structures due to their non-linear nature and random distribution of constituents. Evaluat

Evaluating the Degree of Nonlinearity by Applying the Nonlinear SPC-I Technique in the FEM Simulation of Materials With Breathing Cracks

Autor: SeHyuk Park, Hamad Alnuaimi, Umar Amjad, Tribikram Kundu

Publikováno v: 2021 48th Annual Review of Progress in Quantitative Nondestructive Evaluation.

Detecting internal defects such as fatigue cracks in their early stages is critically important to avoid catastrophic failures. However, detection of micro-scale defects poses a challenge to NDT/SHM (Non-Destructive Testing & Structural Health Monito
