    • Geometrical effect on the behavior of circular and elliptic tubes under dynamic axial loading 

      Fauziah, Mat; Rakhmad Arief, Siregar, Dr.; Khairul Azwan, Ismail, Dr.; Sazali, Yaacob, Prof. Dr.; Othman, Inayatullah, Capt (Rtd) Dr. (Universiti Malaysia Perlis (UniMAP)Pusat Pengajian Kejuruteraan Mekatronik, 2012-02-27)
      A numerical investigation of circular and elliptic tubes is performed under dynamic axial loading using non- linear finite element code LS DYNA. The material of the tubes is treated as piecewise linear ...

    • Numerical analysis of dummy neck for crashworthiness assessment 

      Mohamad Sulaiman, Ibrahim; Rakhmad Arief, Siregar, Dr.; Abdul Hamid, Adom, Assoc. Prof. Dr.; Khan, Shah Fener; Hafizawati, Zakaria (Universiti Malaysia Pahang (UMP), 2009-06-20)
      This paper presents an analysis of numerical child dummy neck and neck injury analysis of the numerical child dummy neck. The neck model is developed using flexible component and rigid body. As for the geometries of ...

      Solin, I. K.; Yolanda, O.; Rakhmad Arief, Siregar, Dr. (AIP Publishing, 2009-07)
      This paper is a study and share information of partial discharge measurement and vibration monitoring on power transformer. Power transformer is one of the critical components in power plant and transmission power system. ...

    • Stress concentration factors of various adjacent holes configurations in a spherical pressure vessel 

      Khairul, Fuad; Rakhmad Arief, Siregar, Dr.; Rangkuti, Ch.; Ariwahjoedi, B.; M, Firdaus (Engineers Australia, 2007-12)
      The analysis of stress concentration factor (SCF) of adjacent holes in a spherical pressure vessel can be approached by considering a thin plate undergoing hydrostatic stresses. This work adopts the approach to investigate ...

    • Study of light vehicle side impact crash simulation test 

      Raja Sharmi, Raja Husin; Rakhmad Arief, Siregar; Khairul, Salleh (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      Crashworthiness is the ability of a structure to protect its occupants during an impact. This is commonly tested when investigating the safety of vehicles. In this study, side impact test finite element models ...
