Effect of friction stir welding tool profiles on mechanical properties of dissimilar welded aluminum alloy plates

Bhanodaya Kiran Babu Nadikudi

The main purpose of the present work is to study the effect of tool pin profiles on mechanical properties of welded plates made with two different aluminium alloy plates.

Progressive failure analysis of laminated plate containing elliptical cutout

Ashok Magar, Achchhe Lal

The prediction of accurate failure strength and a composite laminate failure load is of paramount importance for reliable design. The progressive failure analysis helps to predict…

Punching shear behaviour of flat slabs with different reinforcement schemes: openings and rectangularity effects

Donia Salman, Rabab Allouzi, Nasim Shatarat

The main goal is to investigate the effect of size and location of opening and column size on the punching shear strength. Openings are often needed in order to install mechanical…

Flexural bearing capacity of RC hollow slab beam strengthened by steel plates of different thicknesses

Long Liu, Lifeng Wang, Ziwang Xiao

The flexural reinforcement of bridges in-service has been an important research field for a long time. Anchoring steel plate at the bottom of beam is a simple and effective method…

Pantograph-catenary contact reliability analysis under crosswind

Yong-Hua Li, Yang Cao, Yong-Xin Wu, Xiao-Ning Bai, Jia-Wei Mao

This paper aims to establish the relationship between crosswind speed and pantograph-catenary lateral deviation, as well as quantify the influence of crosswind speed and rod size…
