Aim & Scope

The Transactions of the Korean Society of Mechanical Engineers "B" is a monthly periodical published on the 1st day of each month. The aim of the journal is to provide an international forum for the publication and dissemination of original works that contribute to the understanding of the following fields of mechanical engineering: Thermal Engineering, Fluid Engineering, Energy and Power Engineering, Bio Engineering and Micro-Nono Engineering. Manuscripts may fall into several categories including regular contributed papers, technical papers, solicited/unsolicited reviews or commentaries.

    Kikukawa-Compliance method using a conventional clip-on gauge was employed to investigate fatigue crack growth and crack closure in 2017-T3 aluminum alloy. The crack growth rate plot against stress intensity range .DELTA.K on a log-log diagram exhibits a bilinear form with a transition at the growth rate of 10$\^$-4/ mm/cycle. The bilinear form appears still in the plot of growth rate versus effective stress intensity range .DELTA.K$\_$eff/. Fatigue crack growth rate could be well represented by .DELTA.K$\_$eff. The experimental results indicate that the effective stress intensity range ratio U depends on the maximum stress intensity factor K$\_$max/, but the stress ratio R does not affect U. The crack opening stress intensity factor K$\_$op/ tends to increase with increasing K$\_$max/ and decrease with increasing .DELTA.K.
