ABSTRACT. A methodology is developed for estimating the overall elastic-plastic response of composites which undergo finite plastic deformations, and therefore their effective instantaneous elastic-plastic moduli in a continued plastic flow are of the order of magnitude of the applied stresses.

The methodology also applies to composite elastic solids at finite strains (such as reinforced rubbers). reduces stress concentration, however, the stress concentration factor can go up % of the reduction when plastic deformation exceeds a certain level, as shown in Fig   A combined complex potential-variational solution method is developed for the analysis of unsymmetrically laminated plates with finite planform geometry, subjected to arbitrary edge loads, and with an inclined elliptical by: A rational development of lamina-to-laminate analysis methods for fibrous composites.

Estimation of stress concentration factors by the BJSFM method (Garbo and Ogonowski [3]) allows for this apparent nonlinear behavior in the immediate vicinity of the bolt holes by comparing the laminate stresses with elastic failure criteria at a distance slightly offset from the edge of the hole.

The objective of this paper is to investigate the effects of geometrical parameters such as the edge distance-to-hole diameter ratio {e/d}, plate width-to-hole diameter ratio {w/d}, and the distance between two holes-to-hole diameter ratio {l/d} on stress distribution in a unidirectional composite laminate with two serial pin-loaded holes, analytically and by: Literature review on imperfection of composite laminated plates.

The free-edge effect around holes in composite laminates has recieved less attention than the straight free-edge problem.

Mathematical analysis of free-edge stresses around holes have mostly been numerical. The present work develops a simple approximate solution of the hole problem which allows for low cost computation. The method assumes that only the deviations of the ply stresses from the Cited by: 1.

Usually, the design of composite structures is limited to the linear elastic analysis only. The experimental results discussed in the paper demonstrate the physical non-linear behaviour both for unidirectional and woven roving composites.

It is mainly connected with the micromechanical damages in composite structures, particularly with the effects of matrix cracking modeled in the form of. The text is presented in four parts: Part 1 sets the scene and reviews the fundamentals of composite materials together with the basic nature of FRP and its constituents.
