Functionally Graded Structures

The behavior of functionally graded structures has received a great deal of attention in recent years. Usually, these structures are made out of a composite material with a modulus of elasticity, a Poisson’s ratio, and a density that vary through the thickness. The non-uniformity through the thickness introduces coupling between the transverse deformations and the deformations of the mid-surface. Previous publications have shown how to account for these added complexities and have presented extensive results in tabular form. In this article, available results are used to show that the behavior of functionally graded shells is similar to that of homogeneous isotropic shells. It is well known that for isotropic shells, results can be presented in non-dimensional form so that, once results are obtained for one material, they can be simply scaled to obtain the corresponding results for shells made out of another material. The same can then be done for functionally graded shells. In addition, if functionally graded shells behave like homogeneous shells, no new method of analysis is required. The second part of the paper examines why this is true.

Abstract This paper presents the first estimation for the mechanical properties and the mass density of the masonry of Al-Malwiya heritage minaret. Many approaches are investigated in order to estimate the modulus of elasticity, shear modulus, Poisson’s ratio, and the mass density for this historic masonry. The mechanical properties are estimated by using empirical formulas and analytical equations, while the mass density is estimated after carrying out experimental tests for the extracted samples of the historic mortar. The estimated properties showed relatively low values compared with the newly constructed masonries, but they were interpreted as reasonable for such a historic construction.

This paper deals with an evaluation of long-term experimental work carried out in cooperation with concrete suppliers and a specific company (named Sobriety). The key part of this work is focused on the experimental determination of secant modulus of elasticity and Poisson's Ratio of special concrete (self-compacting concrete, steel fibre reinforced concrete, polymer fibre reinforced concrete, specific high-strength concrete). Two different real-time approaches were used to detect modulus of elasticity. In parallel, both approaches - the (European) standard approach and the DIC (2D DIC; 3D DIC with varying lengths in the vertical direction) - were applied.

The paper deals with the free oscillations of pipelines as thin cylindrical shells with regard to internal pressure. The pipeline is presented in the form of a closed cylindrical shell with a radius of the midline of the cross section. The material is considered isotropic with density, modulus of elasticity, and Poisson’s ratio

Different Ages

In this investigation, the structural design properties of concrete were characterized. Compressive, tensile, and flexural strengths were measured at different ages. In addition, modulus of elasticity, Poisson's ratio, creep, shrinkage, and various other properties were measured. Laboratory results were compared with several structural codes used by engineers for bridge and structural design. The results serve as a reminder that assumed code values can be significantly in error and must be used only in the absence of better data.Key words: concrete, creep, shrinkage, modulus of elasticity, strength, design.
