Abstract

Exact solutions exist for the problem of thick-walled composite tubes if uniformity of geometric and material properties in the axial and circumferential directions is assumed. If solved directly, the resulting system of equations for the boundary and continuity conditions quickly increases in size with the number of layers. This paper shows how the number of unknowns and the matrix size are significantly reduced if a finite element technique retaining the exactness of the solution is employed. It is also demonstrated in some detail how various loading conditions such as non-uniform temperature distributions due to heat flux across the wall, shrink fits, axial force, etc., can be accounted for by finite element formulation.

Design of hybrid steel-composite interference fitted and adhesively bonded connections

Being the static coefficient of friction μS=tan(αS), its value is equal to 0.159 with standard deviation equal to 0.02. To evaluate the coupling pressure due to the interference fit assembly, Lamè's solution for thick walled isotropic cylinders [16] was extended to orthotropic tubes [1,17,18]. The mathematical solution is reported in the Appendix section.
The work deals with the definition of the axial push-out force in hybrid connections realized by means of a carbon-epoxy composite bush which is press fitted into a steel housing and, eventually, supplemented with anaerobic adhesive, in order to obtain an innovative (hybrid) journal bearing. Lamè's solution has been extended to orthotropic material (composite bush) in order to evaluate analytically the coupling pressure due to interference assembly, while experimental campaigns have provided the values of coefficient of friction and of the adhesive shear strength (steel-composite). The mere application of the anaerobic adhesive before the assembly operation does not provide any sensible increase in push out force especially if compared with metal–metal interference connections. In order to take advantage of the adhesive strength, specific hoop channels for the adhesive hosting have been realised on the external surface of the composite bush.
Corrugated laminate analysis: A generalized plane-strain problem

This class includes cylindrical bending [19]. A model for thick-walled tubes whose wall can consist of a most general laminate excludes bending [20]. Then, all displacements, strains and stresses are constant along the circumference and only the longitudinal displacement varies linearly along the tube’s length.
The task of finding a substitute plate model representing the structural properties of a corrugated laminate requires solving of a set of six load cases all of which are generalized plane-strain problems. This work derives a dedicated two-dimensional finite element which is not found in commercial FEM software. It is used to model the corrugated laminate, solve the load cases, and obtain the substitute stiffness matrix entries as a postprocessing task. Displacement constraints map the solid-model response to plate behavior and impose the periodicity and boundary conditions on the unit cell. The new model is verified by comparing its predictions with those of three-dimensional-model FEM simulations, performed with a commercial code, and with a previously existing closed-form model based on thin-shell theory.
A post-processing method for interlaminar normal stresses in doubly curved laminates
2007, Composite Structures
A model for interlaminar normal stresses in singly curved laminates was presented in previous works. This work presents another postprocess method for interlaminar normal stresses in doubly curved and moderately thick laminates. It is based on the through-the-thickness equilibrium equation for arbitrary doubly curved shells. This method is linked with a commercial shell element and works for arbitrary laminates. The interlaminar normal stresses are calculated for two different geometries with different materials, lay-ups, and thicknesses. These results are compared with finite element solid modeling results.
Enhanced model for interlaminar normal stress in singly curved laminates
2007, Composite Structures
An existing model for interlaminar normal stress distribution in singly curved and moderately thick laminates neglects to model the influence of interlaminar shear. This work completes the previous model and validates improvement of accuracy. The new model and a FEM model based upon solid finite elements are used to predict the critical delamination loads observed in experiments which are also described.
Model for interlaminar normal stress in singly curved laminates
2005, Composite Structures
The paper presents a new model for interlaminar normal stress distribution in moderately thick and singly curved laminates. It requires in-plane strain information which must also map the kinematical effects caused by the curved laminate shape. The number of free parameters of the exact solutions for each layer is reduced and determined by a finite-element procedure which is also explained. The results of the mechanical model are compared with FEM results for unidirectional and cross-ply laminates. The new model can be developed for element-level post processing in a FEM program with simple finite structural elements.
