TL;DR: In this paper, the elastic responses of the blistering films are shown to be linear when the film is thick, relatively rigid, or subjected to a large residual stress, and cubic when the films is thin, flexible, or under a small residual stress.

TL;DR: In this paper, a low-speed impact of a one-dimensional sandwich panel by a rigid cylindrical projectile is considered, where the core of the sandwich panel is functionally graded such that the density and hence its stiffness vary through the thickness.

TL;DR: Theoretical moment-curvature relationships for reinforced concrete members with cyclic loading are derived using stress-strain curves for steel and concrete as discussed by the authors. But the results are limited to the case where the concrete is used to prevent buckling of the steel.
Abstract: Theoretical moment-curvature relationships for reinforced concrete members with cyclic loading are derived using stress-strain curves for steel and concrete. The theoretical curves compare well with test results and illustrate the variation in flexural stiffness due to the Bauschinger effect of the steel and to the presence of open cracks in the compression zone of the concrete which may eventually close. These cracks mean that for large portions of the moment-curvature curves after the first yield excursion the moment of resistance is provided by a steel couple alone. During this part of the cyclic loading the main role of the concrete is to prevent buckling of the steel. For beams with a marked difference between the top and bottom steel areas and for columns the moment-curvature loops show a pinching in effect and the loop area is significantly smaller than that of the commonly used elastoplastic idealization.

TL;DR: In this article, the effects of a single-edge crack on the load carrying capacity, the deflection, and the fracture load of a column with a single edge crack have been studied based on column theory together with the well-known relationship between the compliance and the stress intensity factor of a cracked beam.

TL;DR: In this article, a micro-mechanics model for non-isotropic, open-celled foams is developed using an elongated tetrakaidecahedron (Kelvin model) as the repeating unit cell.
