Static response of cord composite plates
Wire rope reinforced composites have many technologically important applications. These composites are used in automobile tires, conveyer belts, and various military components. This particular combination of materials is especially effective when the composite material needs to be strong in …

Secondary Buckling of Laminated Composite Plates
The postbuckling load carrying capacity of composite plates offers immense potential to their applications for loads exceeding their primary buckling load. However, such an efficient and economical usage of these plates can be reliable only if the nonlinear postbuckling behavior of these plates, …

Large-deflection analysis of cord composite plates
Cord composites, which are constructed by embedding cords in a rubber matrix, have been used in industry for many years. This type of composite is strong in extension in the cord direction but very flexible with regard to bending. Previous studies in predicting the elastic constants of wire cord …

Lamb wave propagation in laminated composite plates
Low frequency Lamb waves in composite laminates were investigated theoretically and experimentally. To have a general solution for Lamb wave propagation in multilayered composite laminates is not practical due to a large number of boundary conditions needed to be satisfied at the interlaminar …

Vibration of laminated orthotropic composite plates and shells.
… the analytical solution techniques presented for composite plates and shells deal with either simply supported conditions or boundary conditions with at least a pair of opposite edges simply supported. In the present study, an alternative general approach, combining superposition and state space …

Postbuckling failure of composite plates with central holes
The postbuckling failure of square composite plates with central holes is analyzed numerically and experimentally. The particular plates studied have stacking sequences of [± 45/0/90]₂₅, [± 45/02]₂₅, [± 45/06]₅. and [± 45]₄₅. A simple plate geometry, one with a hole diameter to plate width ratio of …

Dynamic stability of shear deformable viscoelastic composite plates
… is used to analyze the dynamic stability of composite, viscoelastic flat plates subjected to in-plane, biaxial edge loads. In deriving the associated governing equations, a hereditary constitutive law is assumed. In addition, having in view that composite-type structures exhibit weak rigidity …

Thermal buckling and postbuckling of symmetrically laminated composite plates
… and post-buckling of symmetrically laminated composite plates. In this study, thermal buckling is investigated for laminates under two different simple support conditions, fixed and sliding. These laminates are subjected to the conditions of a uniform temperature change and a linearly varying …

Automated design of composite plates for improved damage tolerance
… automated procedure for designing minimum-weight composite plates subject to a local damage constraint under tensile and compressive loadings has been developed. A strain based criterion was used to obtain fracture toughness of cracked plates under tension. Results of an experimental investigation …

Postbuckling Analysis of Delaminated Composite Plates Under Compression (Composite Laminates)
Failure mechanics of delamination problems in composite laminates under compression is investigated. The failure modes in general may include prebuckling, postbuckling, delamination growth and final failure. Buckling load is determined by solving an eigenvalue problem using a subspace iteration …

Analysis of fiber-reinforced composite plates utilizing curvilinear fiber trajectories
Four plates with centrally located circular holes were manufactured using a fiber placement technique. With two plates the fibers were steered around the holes in curvilinear trajectories. With the two other plates the fibers were placed in the conventional straight line format. For the case of the …
