Controlled degradation of the welding parameters is used in this work to produce homogeneous advanced high strength steel (AHSS) resistance spot welds with significant liquid metal embrittlement (LME) inner cracks and study their impact on mechanical behavior. For first time, effect LME damage development monitored using interrupted cross tension tensile shear test. Despite potential stress sta...

In this paper, the influence of small additions Cr, Mo, Cu, Ni, B, Ca, Zr, and Ce on hot ductility advanced high-strength steels (AHSS) has been reviewed. Most these have a positive effect in improving straightening during continuous casting operations should be considered when problems with cracking are encountered. many cases, reason for generally but important improvements is not known certa...

Abstract Horizontal T-foils allow for maximum lift generation within a given span. However, the force on T-foil acts symmetry plane of hull, thereby producing no righting moment. It results in lack transverse stability during foil-borne sailing. In this paper, we propose system, where height-regulating flap trailing edge foil is split into port and starboard part, whose deflection angles are ad...

In this paper, we study the distribution on the eigenvalues of the preconditioned matrices that arise in solving two-by-two block non-Hermitian positive semidefinite linear systems by use of the accelerated Hermitian and skew-Hermitian splitting iteration methods. According to theoretical analysis, we prove that all eigenvalues of the preconditioned matrices are very clustered with any positive...
