“…But no procedure was mentioned to determine the valid radial locations in this works. In contrast, Sarangi et al [35][36][37] presented for the first time a general theoretical methodology based on the finite element analysis to obtain the valid radial locations for the technique of single strain gage proposed by DS. They defined a parameter r max which is the upper bound on the radial location for the strain gage which in turn can be used for locating the optimal or valid radial locations for strain gages.…”

“…To avoid the effects of the strain gradient, threedimensionality and plasticity, the strain location was chosen relatively far from the crack front (Sarangi et al, 2013). The optimum radial location of the strain gage, r, was found using the approach proposed by Sarangi et al (2010Sarangi et al ( , 2013. Gage length of 1 mm was employed to eliminate the strain measure error (Berger and Dally, 1988;Younis and Kang, 2011).…”

This article proposes an alternative model for active repair for an edge-cracked plate with adhesively bonded piezoelectric actuator. It computes the Mode-I stress intensity factor (SIF) produced by the piezoelectric actuators using appropriate derived geometrical weight functions. Furthermore, this article presents an experimental study to verify the proposed analytical model and the finite element analysis using ANSYS software. Therefore, the analytical, finite element and experimental results for Mode-I opening of the crack conditions are demonstrated. Parametric analysis to understand the influence and to study the efficiency of the piezoelectric actuator on mitigation of the Mode-I SIF was conducted. The obtained analytical solution is applicable in the calculation of Mode-I SIF with reasonable accuracy. The result indicated that the maximum reduction of SIF is achieved with the application of high external voltage and thin thickness actuator. The relative errors of the analytical model and the experimental results are less than 10% in all the cases studied in this article.

“…In the study of fracture mechanics by Sarangi et al 2 in strain gauge techniques, they found that the gauges should be placed at appropriate locations and orientations with respect to the crack tip, and at high strain gradient areas; however, they should not be placed on too large strain gradient areas so as to avoid averaging errors caused by plasticity and three-dimensional (3D) effects. In automated production systems, it is vital to obtain reliable machining signals since the tool wear has great direct effects on quality of the machined parts.…”

The aim of this study was to determine the the optimum locations to mount the sensor for measuring the cutting tool deflection during turning process using finite element method simulation. In this study, stress analysis had been conducted using Autodesk Inventor Professional 2010 integrated with ANSYS software. The simulation results were validated using a strain gauge as the sensor for the detection of cutting force signal during the turning of hardened plain carbon steel JIS S45C using carbide tool. Two strain gauges were mounted on the tool holder at two defined locations I and II, at distances of 37 and 47 mm, respectively, from the cutting point. Only one set of cutting parameters was conducted at spindle speed, N ¼ 1000 rpm, feed, f ¼ 0.25 mm/rev and depth of cut, d ¼ 0.80 mm. The turning process was stopped and the insert discarded when the average flank wear, VB m , reached 0.30 mm. The main cutting force, F y , and the feed force, F x , for each machining run were measured, collected and analysed at locations I and II. It was found that when strain gauges were placed at a distance of approximately 43 mm from the cutting point, it was the optimum location for sensing the cutting force signals.
