“…Damage is simulated as a hole with radius of 0.02m. The modeling method, employing standard and explicit FEM represent the modeling procedure used in the paper [32] which was verified by the experiment on the concrete beams. The model of PZT SA was made in the software package ABAQUS/STANDARD taking into consideration electromechanical characteristics of PZT materials, using the combination of mechanical equilibrium and the equation of equilibrium of electrical flux.…”

Monitoring of structures implies integration of sensors and actuators, smart materials, data transfer as well as computer analyses and simulations with the purpose of damage detection, localization, assessment and prediction of the state of damage at the certain moment and in time. This paper presents the application of the explicit finite element method for modeling of the wave propagation. The examples of concrete plates and thin steel plates in which the propagation of the Lamb waves occur were analyzed. Explicit finite element method was shown to be very efficient even for the waves in ultrasound range. Efficiency, ease of the use and reliability of the wave propagation modeling by the explicit finite element method can contribute to the development of a new and the improvement of the existing methods for the monitoring of structures. The main purpose of this paper is to demonstrate a waveform propagation model using an explicit FEM in ABAQUS software.

“…The most commonly used numerical approach for wave propagation modeling is certainly the FEM . In general, two separate methods for direct time integration of finite element solutions of structural dynamics and transient wave propagation problems are used: the implicit FEM and the explicit FEM (EFEM) . A time integration method is implicit if the solution procedure requires the factorization of an “effective stiffness” matrix and is explicit otherwise …”

This paper presents an experimental–numerical analysis of damage localization of concrete plate‐like elements on the basis of hybrid approach. The proposed hybrid approach uses the fast discrete wavelet transform, energy approach, and time of flight criterion for the purpose of localization of single and multidamage problems inside or on the periphery of concrete elements. Verification of the proposed damage localization approach has been performed under laboratory conditions using a laser scanning‐based system with piezoelectric excitation of the wave propagation. Numerical simulation of the wave propagation is performed using the explicit finite element method using 3D models with linear‐elastic material model of concrete with Rayleigh damping. The Rayleigh damping coefficients are determined on the basis of experimental data and implemented in numerical models. Validation of the numerical model is conducted, based on the comparison with sensor output signals obtained through experimental measuring and a very good agreement of results is obtained. The proposed hybrid approach to damage localization is verified using 15 different models/specimens, varying the number, shape (circular or notched), and position of damage, as well as the number and placement of actuators/sensors. For all the analyzed scenarios, the hybrid approach successfully localized the damage even for the least number of used sensor positions. In the models with the circular damage, the damage image created on the basis of the hybrid approach is almost identical to the actual shape of the damage, indicating a good potential of the method for damage localization.

“…The displacement variation function used in the analysis is the 3.5-cycle Hanning windowed tone burst signal with the duration of 3.5e -5 sec and central frequency of 100 kHz. The modelling method, employing standard and explicit FEM represents the modelling procedure used in paper [11] which was verified by an experiment involving concrete beams. Concrete and reinforcement were modelled as linear-elastic materials, and their characteristics are presented in Table 3.…”

“…Development of numerical models for PZT SA, and for propagation of waves through RC, can be of great importance for the development of the method, and for practical implementation of these models for the detection, localization and determination of damage size. Numerical models of PZT SA, and the models of wave propagation through concrete beams in damaged and undamaged condition, are presented in paper [11] using the explicit finite elements methods (EFEM). Numerical model of PZT SA for monitoring shear seismic stresses in structures using d 15 piezoelectric mode is presented in paper [12], while the model for monitoring normal seismic stresses is developed and presented in paper [13].…”

Detection of damage to reinforced-concrete structures using piezoelectric smart aggregatesThe implementation of active monitoring systems to diagnose damage to reinforced concrete structures using piezoelectric smart aggregates, and based on wave propagation, ranks among the world's most advanced research activities. Original models, with parametric analysis of the damage index variation problem, depending on the size, position and orientation of cracks, are presented in the paper. Numerical modelling of wave propagation in reinforced concrete is conducted using the explicit finite element method, which is highly effective for this purpose. Otkrivanje oštećenja armiranobetonskih konstrukcija primjenom piezoelektričnih pametnih agregata Primjena aktivnih sustava monitoringa kod otkrivanja oštećenja armiranobetonskih konstrukcija pomoću piezoelektričnih pametnih agregata, kao i na temelju širenja valova, trenutačno su najsuvremenija istraživanja u svijetu. U radu su predstavljeni originalni modeli s parametarskom analizom problema promjene indeksa oštećenja konstrukcija u ovisnosti o veličini, položaju i orijentaciji pukotina. Numeričko modeliranje širenja valova u armiranom betonu izvedeno je eksplicitnom metodom konačnih elemenata koja je veoma učinkovita za ovu uporabu.
