I began my career as an academic at Universiti Teknologi Malaysia (UTM) in September 2005, serving as a tutor for the IT Unit in the Faculty of Civil Engineering. During my time in this role, I fully immersed myself in the academic culture of UTM, constantly seeking opportunities to expand my knowledge. In 2008, I was thrilled to be promoted to the position of lecturer after completing my Master’s degree in March of that year. As a lecturer, I have had even more opportunities to contribute to the development of both my students and the university as a whole, particularly through teaching and supervising computational-engineering-related subjects... read more…

N-RPIM for structural analysis
The study proposes a new way of combining two mathematical techniques, NURBS and RBF, within the RPIM framework. NURBS are used to model the geometry of the problem domain exactly, while RPIM is used for field variables interpolation. This new approach is called...

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...

Radial Basis Function (RBF)
Radial Basis Function (RBF)The radial basis function (RBF), also known as the Radial Point Interpolation Method (RPIM), is a meshfree method used to construct an interpolated function to fit a curve. It uses a set of radial basis functions to interpolate between nodal...
Point Interpolation Method (PIM)
The point interpolation method (PIM) is a meshfree method used for fitting a curve based on a set of nodal values at specified locations. The PIM uses polynomial interpolation to fit the curve, and the number of polynomial terms required increases with the number 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...
