    • Elastic crack interaction limit of two interacting edge cracks in finite body 

      R., Daud; M. A., Rojan; A. K., Ariffin; S., Abdullah (Universiti Malaysia Perlis (UniMAP)Pusat Pengajian Kejuruteraan Mekatronik, 2012-02-27)
      In certain range of crack interval ratio and crack width ratio, the neighboring cracks will affect the changes of stress field interaction around the crack tip, thus induced significant changes in stress intensity factor. ...

    • Microstructure analysis on spring steels due to fatigue failure 

      F.N., Ahmad Refngah; S., Abdullah; A., Jalar; L.B., Chua (Universiti Malaysia Perlis, 2009-12-01)
      Fatigue on metal is one of the common phenomenons that people have been continuously exploring and trying to describe the whole process. This type of failure occur when component are subjected to cycle loading that is ...

    • A study on fatigue time series using cross correlation function 

      Lennie, Abdul; S., Abdullah; Mohd Nopiah, Z.; M. N., Baharin (Universiti Malaysia Perlis (UniMAP)Institut Matematik Kejuruteraan, 2010-06-02)
      This paper presents the analysis on variable amplitude (VA) loading strains data using cross correlation function (CCF). CCF is a method to measure a similarity of two fatigue time series as a function of a time-lag ...

    • Using a fatigue data editing approach for analysing cycle sequence effects in variable amplitude road loadings 

      S., Abdullah; J. C., Choi (The Institution of Engineers, Malaysia, 2006-06)
      This paper presents the analysis of cycle sequence effects using variable amplitude (VA) fatigue loadings extracted from a wavelet-based fatigue data editing algorithm, known as Wavelet Bump Extraction (WBE). This algorithm ...
