The crimping process using a polyurethane tool and hydraulic pressure can be used in the assembly of tubular components. This crimping operation was evaluated with the aid of the finite element method (FEM) and its application to the assembly of tubu

The crimping process is used often in the assembly of tubular components. In this study, with the aid of the finite-element method (FEM), the mechanical crimping operation was evaluated and optimized for a specific application. The effect of various

Residual stress states within certain classes of polymeric adhesives andcoatings subjected to cyclic temperature conditions can becomeincreasingly tensile with exposure to cyclic temperature conditions.Under some conditions, these tensile stresses ar

Quantification of the coefficient of thermal expansion (CTE), the stress-free temperature, and the residual stress state is of critical importance for many applications involving bonded systems such as coatings, adhesives, and other laminated systems

We analyze the e!ect of inertia forces on damping induced during large shearing deformations of an isotropic, incompressible and homogeneous viscoelastic layer constrained between two rigid circular cylinders. The layer is deformed by holding the inn

We analyze the damping induced by a homogeneous and isotropic viscoelastic layer embedded between a rigid solid cylinder of radius r 1 and a homogeneous and isotropic elastic hollow cylinder of inner and outer radii r 2 and r 3 respectively. The comp

For simple shearing and simple extension deformations of a homogeneous and isotropic elastic body, it is shown that a linear relation between the second Piola-Kirchhoff stress tensor and the Green-St. Venant strain tensor does not predict a physicall

We study the thermodynamics and stability of a history type viscoelastic solid with an exponentially decaying relaxation function. The relaxation modulus must be non-negative and the Helmholtz free energy must be at a minimum at equilibrium in order

We study the radial motion of an incompressible viscoelastic spherical shell with a nonconvex strain energy function that models a material that can undergo a phase transition. In addition to the classical Newtonian viscosity for viscoelastic materia

We study the thermodynamics and stability of a viscoelastic second grade solid whose action is characterized by two microstructural coefficients α 1 and α 2 in addition to the Newtonian viscosity μ. We show that it is both necessary and sufficient
