A constitutive theory is proposed for FRP laminated composite materials that is designed to account for both temperature and strain rate dependent response, such as would occur during, and after, exposure to the elevated temperatures due to fire. The theory is physically based, and in particular, is based on a kinematical framework fixed on the fabric laminates; full accounting of laminate reor...

Methods for veneering vital ~eeth have progressed dramatically. The practicing dentist can now choose a veneering process that will best suit the esthetic needs of each of Ins patients. Patients who have dental esthetic problems can now find a reasonable solution to their problems without unnecessary reduction of

AIM This study evaluated the bond strength and failure mode of enamel/resin-based composite veneers bonded with three different dual cured resin adhesive systems. METHODS AND MATERIALS Standard preparations for laminate veneer restorations were made on 30 human central incisors using depth cutting burs (0.5 mm depth at the incisal area and 0.3 mm at the gingival area). Thirty indirect laminat...

This paper offers a detailed, quantitative and exhaustive experimental comparison in terms of mechanical properties of three different layouts of carbon composite materials (CFRP) used to strengthen existing old timber beams highly affected by diverse natural defects and biological attacks, testing the use of pultruded laminate attached on the tension side of the element (LR), CFRP fabrics tota...

When a definitive aesthetic treatment is determined, it is crucial to grant the patient's wish with the necessary dental treatment. Thus, conservative treatments that are the solution to aesthetic problems involving morphologic modifications and provide the result that the patient expects should always be the first therapeutic option. In this context, ceramic laminate veneers, also known as "co...

The use of bistable laminates is a potential approach to realize broadband piezoelectric based energy harvesting systems. In this paper the dynamic response of a piezoelectric material attached to a bistable laminate plate is examined based on the experimental generated voltage time series. The system was subjected to harmonic excitations and exhibited single-well and snap-through vibrations of...

Using variational mechanics we present mathematical bounds on the effective modulus of a crossply laminate containing microcracks in the 90◦ plies. An average of the two bounds provides an effectively exact solution to the modulus reduction problem. The problem of predicting microcracking is reduced to finding the energy release rate for formation of a complete microcrack. From the bounds on ef...
