A generalized interface model for joints and cracks in quasi-brittle materials is formulated. The proposed model marries an existing fracture mechanics based one developed for monotonic loading of concrete with another frictional based model de[...]

Approximate buckling formulas for shear—flexural buckling of cantilever columns subjected to a uniformly distributed load are derived, based on Timoshenko’s energy method. In this method the deflection curve at buckling is approximated by a tria[...]

The effect of V-notches (or reentrant corners) on fracture propagation has been analyzed for brittle materials, but not for quasi—brittle materials such as concrete, marked by a large material characteristic length producing a strong size effect[...]

This paper presents a new model for nonlinear analysis of reinforced concrete beam.columns with bond—slip. The model is derived from a two-field mixed formulation with independent approximation of forces and displacements. The state determinatio[...]

A method is presented for identification of elastic constants for composite materials using three measured strains of a single angle-ply laminate subjected to tensile testing. In the proposed method, the trial material constants of the angle-ply[...]

A new theory of composite damage mechanics is developed. A material with damage is considered as a composite comprised of two different phases (called matrix and inclusion). Both phases are linearly elastic isotropic materials. The matrix is con[...]

Traditional deformation parameters such as drained, unjacketed, and pseudo-bulk compressibilities are developed for a saturated porous medium, assuming they can be uniquely determined by measuring the liquid pressure, confining pressure, and cha[...]

This is a practical paper which consists of investigating fracture behavior in asphalt concrete using an intrinsic cohesive zone model (CZM). The separation and traction response along the cohesive zone ahead of a crack tip is governed by an exp[...]

A new full two-dimensional semianalytical method is developed to rigorously and efficiently solve the problem of a rigid cylinder rolling with any given constant speed over a viscoelastic foundation of finite thickness. In this new method, the s[...]

The contact force model consisting of a linear spring dashpot with a frictional glider has been widely adapted to simulate granular flows. Real contact mechanics between two solid bodies is very complicated. Extensive theoretical and experimenta[...]

A two-compartment analytical model was developed to estimate the turbulent dissipation rates in a standard jar stirred by a radial impeller. A simple numerical simulation was also performed to support the analytical arguments. Results of the num[...]

In the technical note a single-degree-of-freedom system with stationary random temporal variations of its stiffness is considered. The problem of short-term instability is studied. The analysis is based on a parabolic approximation of the random[...]

A fully nonlinear finite-element analysis for postbuckling response of a moderately thick imperfect ring under applied hydrostatic pressure is presented. The fully nonlinear theory employed here, in contrast to the von Karman approximation gener[...]
