Kankan Ji, Xingquan Zhang, Shubao Yang, Liping Shi, Shiyi Wang, Yuguo Wu

The purpose of this paper is to evaluate surface integrity of quenched steel 1045 ground drily by the brazed cubic boron nitride (CBN) grinding wheel and the black SiC wheel…

The shockwave dispersion/attenuation potential of a protective structure made of a chemically reactive mixture: A continuum-level analysis

Mica Grujicic, S. Ramaswami, Jennifer Snipes

In the recent work, a new blast-wave impact-mitigation concept involving the use of a protective structure consisting of bimolecular reactants (polyvinyl pyridine+cyclohexyl…

High-rise building subjected to excessive settlement of its foundation: a case study

Lan Lin, Adel Hanna, Anup Sinha, Lucia Tirca

Differential settlement between foundations’ elements induces additional stresses in the structural elements. In general, the amount of settlement that a structure can undergo…

Damage detection in steel structures with semi-rigid connections using unscented Kalman filter

Hasan Katkhuda, Nasim Shatarat, Khaled Hyari

The purpose of this paper is to detect damages in steel structures with actual connections, i.e. semi-rigid connections. The method will detect the damages by tracking the changes…

On the effect of hydrostatic stress on fatigue crack propagation

Nikos P. Andrianopoulos, Aggelos Pikrakis

The purpose of this paper is to study mutual interaction between von Mises equivalent and hydrostatic stresses at the crack tip area of an elastoplastic material in order to…
