Inspecting Marquetries at Different Wavelengths: The Preliminary Numerical Approach as Aid for a Wide-Range of Non-destructive Tests

The present study is based on the non-destructive inspection of two marquetries representing arms’ coats, which were produced by the Technical University in Zvolen (Slovakia) and tested under laboratory conditions. The aforesaid samples were made of traditional European and exotic wood species, while the veneers of the decorative layers were prepared through the technology cutting technique, emphasizing in such a manner the wooden texture. One sample was a defect-free panel, while the second one consisted of three sub-superficial flaws and one superficial putty insert, added during the manufacturing stage. The samples were inspected by different non-destructive techniques, such as visible imaging, ultraviolet testing, near-infrared reflectography and transmittography, infrared thermography, holographic interferometry, digital image correlation, laser speckle contrast imaging and ultrasonic testing. Sometimes a comparison was not performed, by avoiding unnecessary data processing. Numerical simulations focusing on the optimization of the provided thermal flux anticipated the experimental results. The latter analysis proved the necessity for the integration of experimental and numerical testing in similar case studies. A peculiarity of this work is the additional creation of an ad hoc Matlab\(^\circledR \) code, written under the LSCI conditions, which identifies the wooden texture. The interactive methodology applied in the present study verified the synergy of the selected inspection methods enabling the production of a complete view for the preservation state of the inspected marquetry samples, through the comparison and/or the correlation of the individual informative content produced by each inspection procedure.

Application software system based on direct slicing for rapid prototyping

A direct-slicing approach might improve the accuracy and quality of small, complex parts produced with rapid prototyping technology. An application software based on direct slicing for rapid prototyping was used on the foundation of PowerSHAPE models. Lines, conic arcs and cubic bezier curves were adopted as the basic elements describing the direct-slicing contours. Moreover, a scheme to carry out subdivided software development was proposed. A picture (PIC) format file was selected as an interface for the slicing data, and a macro-AutoSection software, which collects the direct-slicing contour data of arbitrary complex computer-aided design models and provides power to produce the direct-slicing PIC files, was developed. On the above basis, an application software called PDSlice based on direct-slicing data processing was developed for the commercial selective laser sintering machine HRPS-III, which was made at the Huazhong University of Science and Technology (HUST), P. R. China. The major input and output interfaces as well as the PIC model reconstruction method of the PDSlice are described. Furthermore, a batch of direct-slicing polymer parts were successfully fabricated with the selective laser sintering machine. The application example shows that the accuracy and surface finish of three-dimensional complex curvature surface parts fabricated with the application software system based on a direct-slicing format were better than the application software system based on a stereolithography (STL) format.     

Termites live in a material world: exploration of their ability to differentiate between food sources.

Drywood termites are able to assess wood size using vibratory signals, although the exact mechanism behind this assessment ability is not known. Important vibratory characteristics such as the modal frequencies of a wooden block depend on its geometry and boundary conditions; however, they are also dependent on the material characteristics of the block, such as mass, density and internal damping. We report here on choice experiments that tested the ability of the drywood termite Cryptotermes secundus to assess wooden block size using a solid wooden block paired with a composite block, the latter made of either wood and aluminium or wood and rubber. Each composite block was constructed to match mass or low-frequency vibratory modes (i.e. fundamental frequency) of the solid wooden block. The termites always chose the blocks with more wood; they moved to the solid wooden blocks usually within a day and then tunnelled further into the solid wooden block by the end of the experiment. Termites offered composite blocks of wood and rubber matched for mass were the slowest to show a preference for the solid wooden block and this preference was the least definitive of any treatment, which indicated that mass and/or damping may play a role in food assessment. This result clearly shows that the termites were not fooled by composite blocks matched for mass or frequency, which implies that they probably employ more than a single simple measure in their food assessment strategy. This implies a degree of sophistication in their ability to assess their environment hitherto unknown. The potential importance of alternative features in the vibrational signals is discussed.
