The goal of this study was to validate the results from infrared thermographic experiment by strain gauge experiments and finite element analysis (FEA) in a carbon epoxy composite plate within the linear elastic limit. A FE model of the plate was first developed and subjected to static loads. The strain values were recorded at four distinct points. Then an experiment using strain gauges was carried out for similar loading conditions and the strains were noted for the corresponding locations. The slope of the correlation plot between the FEA and strain gauge static results indicated that, although the strain gauge experimental values had an overall tendency to overestimate the strain, there was a strong correlation between the data as exhibited by the Pearson coefficient R² = 0.99. Then the stresses calculated from the strain gauge experiment under cyclic tensile loads were used to validate the results from lock-in thermography. These results also showed good agreement as R² was 0.87 and strain gauges experiement tended to underestimate the stress values. From this study, it can be concluded that lock-in thermography can be used to assess stresses in biomaterials used in medical application.

“…Maintenance is an increasing challenge for many industries other than facilities management. In the aviation industry Larsen et al (2001) observe that many aircraft are operating beyond their model design service objectives (DSOs), often in the hands of a second or third operator. Of all the commercial aircraft flying, approximately 20 per cent are in the aging category.…”

“…We used to pull the plane into a hangar, take three weeks to instrument it and then take another week for measurements,'' says Eccles, senior principal engineer for flight test at Boeing Commercial Airplane Group (Seattle).``Now we expect the whole process to take about one week. And we'll get better data and save tens of thousands of dollars in the process (Larsen et al, 2001).…”

Facilities managers have a host of skills to sustain the functionality of complex buildings, often not provided by them directly, but by the team of specialists they draw upon to effectively plan for the future, whether the resource be money, space or technology. Building intelligence presents a challenge in terms of understanding a wholly new approach to the building management. This paper asks if the intelligent building of today meets the needs of the facilities management team. Does it enable them to manage their asset more effectively? New technologies are converging that will enable a radically new approach to maintenance, enabling remote smart sensing or remote condition based monitoring (CBM). Some of the design and economic issues that arise from this radically new approach to managing built assets are highlighted and the possibilities for a maintenance environment, where wires, power cables and data loggers become a thing of the past, is described.

“…The adverse outcomes of this strategy were high downtime and increased lifecycle costs. A study carried out by Boeing in 2000 revealed that more than 50% of the aircraft flying with various airlines across the globe have gone out of production [1]. Additionally, many of these aircraft have completed their assigned service lives.…”

In recent years aircraft maintenance practices have been influenced by changes in aircraft design philosophy and improvements in engineering technology. Advances in manufacturing techniques and material specifications have made it less necessary to carry out frequent disassembly of aircraft and components to establish confidence. The need to be competitive and to reduce costs has meant that the aviation industry has sought to gain advantage from these improvements by moving from time consuming and cost extensive, invasive maintenance to a philosophy of on condition maintenance (OCM). The research is aimed at highlighting an OCM based maintenance methodology by carrying out an extensive study on structural integrity of various vintage Chinese fighter aircraft. The study finds that the structure of Chinese fighter aircraft is robust and is capable of flying for more hours/years than specified by OEM. The study will help air forces operating the ageing Chinese fighter aircraft in extending the lives of their respective fleets well beyond the OEM prescribed limits.
