The effect of bar sealing parameters on the heat seal strength of oriented polypropylene (OPP)/metallic cast polypropylene (MCPP) laminate film was investigated. Based on the results obtained from the parametric study, a bar sealing process window was developed. All points drop within the process window are combinations of platen temperature and dwell time that produce acceptable heat seal. Opt...

School children often encounter traumatic injuries like a crown fracture. They create serious functional, esthetic and psychological problems. Achievement of promising restoration that preserves its aesthetics and strength is the greatest desire for both children and their parents and is a challenging task for the dentist. The restorative options in these cases usually include composite resin a...

In the centrosymmetric title compound, [Cu(C5H11N2O2)2], the Cu(2+) ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N-O groups of two N-nitroso-N-pentyl-hydroxy-laminate ligands [Cu-O = 1.9042 (17) and 1.9095 (16) Å]. The hy-droxy-laminate monoanions are bidentate chelating ligands. The Cu(2+) cations form stacks alo...

The literature has described the clinical aspects of the laminate veneer restoration; however, the laboratory preparation of these veneers has not been detailed This paper outlines a step-by-step laboratory technique for the construction of a commercially available laminate veneer, Mastique.® J_Jaminate veneers have been successfully used on patients with hypoplasia, tetracycline staining, fluo...

In this research, effect of opening on the buckling of FMLs (Fiber Metal Laminate) is studied. Samples are made of a laminate, epoxy resin reinforced with four layers of woven basalt fibers, inserted between two Al plates. Different samples are prepared, tested and studied; one group without opening and the other two groups with circular openings of radii 10 and 20 mm. In all samples buckling i...

This article contains derivation of propagation factors and Fourier series for harmonically time varying, traveling electromagnetic fields in a plate and a laminate with rectangular cross sections, isotropic materials and infinite length. Different and quite general fields are taken into account on all boundaries. Choices of boundary conditions and continuity conditions are discussed. Certain c...

Composites show two distinctive features that affect the way in which they are optimized. Firstly, manufacturing strongly interacts with structural performance. Secondly, composites can be described at different scales. This article summarizes contributions that address both features. It is shown how design guidelines can be accounted for in laminate blended design through stacking sequence tab...

Structural optimization using computational tools has become a major research field in recent years. The paper deals with a sizing optimization analysis of laminated circular cylindrical shell. For thin-walled shells, the classical shell theory is capable of accurately predicting the shell behavior. The weight minimization subjected to displacement constraint within the numerical optimization o...
