Reliability Analysis for Transient Stress Wave in Elastic Laminated Composites,, by applying a first-order perturbation method to a well-known shear-lag model. The analyzed standard deviations of the stress wave correspond to the rate of change in the mean stresses, and indicate the peak at the position close to the wave fronts. The peak values account for the high rates signi

Safety Factor and Reliability,r relates to the disperse degree of strength and load and the value of required reliability of structure. Several failure modes of laminates, different load groups and the effect of the structural parameters of laminates are considered. The characteristic of safety factor is convenient for applicati

Reliability of Composites Based on Micromechanically Predicted Strength and Fatigue Criteria,eory, are derived. Usually, the verification of the predicted strength is performed with respect to mean values of the measured data. Yet, due to the scattering of the latter, the reliability of the theoretical prediction is determined in this paper by studying the randomness effects of the various

Finite Element and Experimental Studies on an Orthotropic Disc,. In the static tests, radial and circumferential strains at a point near the hub of the disc due to a point load applied at the outer rim are measured and compared with finite element results. A reasonable degree of agreement is seen between the two. In the dynamic tests, the natural frequencies of

Performance of Glass Fibre-Vinyl Ester Composite Tubes Crushed Using Internal Mandrels,main types of trigger geometry have been determined. For crushing against a flat platen, the initial chamfer angle has a significant effect on the crush load required to initiate crushing but does not affect the progressive crush load. A similar effect occurs for the internal mandrel trigger. Howeve

Repair of Delaminations and Impact Damage in Composite Aircraft Structures,by completely infiltrating the matrix cracks and delaminations with a specially formulated epoxy resin. Tests are described for evaluating the ability of the repaired laminates to sustain (a) in-plane compression loads, (b) interlaminar shear loads, and (c) low velocity impact. The experimental resu

The impact force could be reduced without appreciably affecting the energy absorption by putting shallow notches on the inside of the ring by carrying out sequent cracking caused by debonding dependent on the stress concentr

Hygrothermal Effects on the Linear and Nonlinear Analysis of Composite Plates,m transverse load is evaluated via the classical laminated plate theory and the von Karman larger deflection theory, respectively. It is shown that the classical laminated plate theory may be inadequate for the analysis of several composite laminates, even in a small deflection range. The influence
