    • Dynamic model and simulation on attitude menoeuvring of flexible satellite 

      Teoh, Vil Cherd; Sazali, Yaacob, Prof. Dr.; Shahriman, Abu Bakar, Dr.; Rakhmad Arief, Siregar, Dr. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      Flexibility has gained much interest in satellite design in recent years due to its capability to accommodate much for functionality with minimum trade-off. A flexible satellite is satellite that consists of many movable ...

    • Dynamic splitting-tensile test and numerical analysis for brittle materials 

      Rakhmad Arief, Siregar, Dr.; Daimaruya, Masashi; Khairul, Fuad (AIP Publishing, 2007)
      This paper is concerned with the dynamic splitting-tensile test for brittle materials. An experiment on the dynamic splitting-tension has been performed on cylindrical concrete specimens by utilizing a Split Hopkinson ...

    • 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 ...

    • Partial discharge measurement and vibration monitoring on power transformer case study on power transformer with high level noise (75.22 dB) 

      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 ...
