In contrast to a homogeneous isotropic elastic medium with only two elastic constants, a linear elastic micropolar solid is characterized by six such constants. To evaluate these constants it is necessary to solve selected boundary-value problems in

The method of singular surfaces is used to obtain expressions for the amplitudes of weak discontinuities reflected from or transmitted across interfaces between solids of dissimilar elastic-plastic properties. Here weak discontinuities are taken to m

At IC package lead counts above 100, the limiting factor for bond densification in single layer packages with gold wire interconnections shifts from pad pitch to a combination of lead tip pitch and wire length. To quantify this effect, the densificat

Load-lateral deflection curves are developed for a pressurized tube of circular cross section under combined bending and compression. The tube walls are assumed to have negligible compressive strength so that wrinkling develops if the stress tends to

Formulas are derived which describe the dynamic response of a ring of rigid-plastic material which is subjected to an arbitrarily distributed impulse load. When the impulse is distributed over half the ring in a cosine fashion, the final deformation

A long, thin-walled cylindrical shell is loaded by a uniform external pressure. Equations are developed for the time behavior of the shape of the cross section under the following conditions: (a) the shell material exhibits only secondary (steady) cr

The Griffith theory for unstable crack length is modified to take into account the effect of residual (self-equilibrating) stresses. An expression relating the uniform stress, physical properties of the material, critical crack length, and the equili

The known solution for the plastic instability failure of an infinite cylell unerinternal pressure is extended to shells of finite length. An incremenl of plasticity is used in the analysis, in conjunction with Trescandio. IT I CONSIDERED THAT THE SH
