I started my carrier as an academician in Universiti Teknologi Malaysia (UTM) since September 2005 as a tutor of IT Unit in Faculty of Civil Engineering. I used that opportunity to really get involved with academic culture in UTM, at the same time strengthened my knowledge as much as possible.
.
Later in 2008, I was very glad to be appointed as a lecturer at UTM Skudai after completing my Master’s degree in March 2008. This time,
I had more opportunities to contribute on the development of students and the university, especially in teaching and supervision of students on IT-related subjects. read more…

FEM Book (2D)
This book can be considered as an extension to the previous publication (Finite Element Formulations for Statics and Dynamics of Frame Structures) as it dwells on two-dimensional formulation of continuums. Also, the discussion has been extended to nonlinear...
FEM Book (1D)
This book has evolved from a series of lecture notes of the first author refined over the period of ten years with the co-authors. It revolves around frame structural analysis, both statics and dynamics. In Chapter 1, the book begins with the basic concepts of...

FB Live [MSNM group] – Numerical Methods: How it works?
In the live videos, I tried to explain how does numerical methods (in computational mechanics) work, in a general way of discussion.. Numerical methods always start 'backward' by having an assumed solution first, and some ways in the process, they try to make the...
Plotting deformation of frame structure (FEM)
This is a MATLAB code to plot a deformation of planar frame structure. Since the formulation involves transformation of local elements to a global system, plotting using a simple w(x) versus x is not possible.. We need to transform back the DOFs obtained in the global...
