Abstract: Several continuum methods for torsional analysis of slender perforated cores are described. First, the open section torsion‐bending theory, which neglects shear deformations, is described. It is then modified to consider ...

Abstract: A stiffness approach is presented for computing the solution of beams on variable Winkler foundation. The solution may be achieved using only a small number of elements along the beam. Accuracy ...

Abstract: This paper is concerned with the bending problem of micro- and nanobeams based on the Eringen nonlocal elasticity theory and Timoshenko beam theory. In the former theory, the small-scale effect is taken into consideration ...

Abstract: A risk assessment procedure is presented that is proposed for the numerical rating and ranking of hazardous material sites in terms of their relative groundwater contamination potential. The assessment procedure has three ...

Abstract: In the San Francisco Bay Region, the Regional Water Quality Control Board is now regulating approximately 140 sites where toxic chemicals have contaminated groundwater. Many of these were located through the Board's ...
