The influence of mono- and diglycidyl diluents on the adhesion, deformation strength, and dynamic mechanical properties of the adhesive composition based on a product previously prepared by the thioetherification reaction between epoxy resin and liquid thiokol has been investigated. It has been shown that the introduction of the diluents into the composition leads to an increase in the tensile strength, failure strain, and the work of fracture of the material at a moderate change in the adhesion strength. The magnitude of the effect depends on the chemical nature of the diluent. 相似文献

The exact analytical solution of a nonlinear boundary-value problem is used to study the effect of a generalized geometric parameter, which characterizes thickness and curvature, on the subcritical and postcritical deformation of a hinged infinite noncircular cylindrical shell. The load on the shell is nonuniformly distributed over its cross section. The deflection of the shell is plotted for various values of the geometric parameter 相似文献

An approach to solving two-dimensional stress-strain problems for orthotropic conical shells of variable thickness in a refined
formulation is developed. The approach is based on the spline-approximation and the stable discrete-orthogonalization method,
which is used to solve the one-dimensional problem. The dependence of the deflection and stresses on the thickness and apex
angle of a shell of constant volume is given as an example

The bending problem for laminated orthotropic trapezoidal plates of variable thickness is solved by parametrizing the domain of interest and reducing the two-dimensional boundary-value problem to one-dimensional using the spline-collocation method. The resulting problem is solved by the stable discrete-orthogonalization method. The influence of orthotropy and the variability of the thickness on the displacement and stress fields is analyzed__________Translated from Prikladnaya Mekhanika, Vol. 41, No. 4, pp. 85–93, April 2005. 相似文献

A procedure is proposed for solving two-dimensional boundary-value problems on the stress-strain state of open and closed
noncircular cylindrical shells of variable thickness under surface loads. The solution is based on the use of the spline-collocation
method along the directrix and the method of discrete othogonalization along the generatrix. Examples of solutions for ellipsoidal
shells of variable thickness are given.

The stress-strain state of a shallow shell with rectangular planform and varying thickness is analyzed in a refined formulation
for different boundary conditions. A numerical-and-analytic method is developed based on the spline-approximation and discrete-orthogonalization
methods. The stress-strain state of shallow shells with thickness varied without change in weight is analyzed
