Keynote Speaker

Professor Dr. Mohd Nasir Tamin

Biography:

Professor Dr. Mohd Nasir Tamin is a senior academic and researcher in Mechanical Engineering and Applied Mechanics, with a Ph.D. from the University of Rhode Island, USA (1997). His career includes significant roles, including the Head of Department and Deputy Dean of Research and Innovation at the Faculty of Mechanical Engineering (UTM), and Director of the Center for Composites (UTM).

Prof. Nasir’s research team activities focus on the development of constitutive and damage models for alloys and fibrous composite laminates. The materials damage models are incorporated into Finite Element codes for reliability assessment of structures.

Prof. Nasir leads his research team on a few successful research collaborations with industries including Intel Technology on the development of a validated methodology for reliability prediction of microelectronic BGA packages and TSV interconnects, with Kiswire (Korea) for fatigue life improvement of steel wire ropes, and with the Aerospace Malaysia Innovation Center (AMIC) for development of fatigue damage models of CFRP composite laminates.

Topic: Framework for Certification of Advanced Structural Systems by Finite Element Simulations

Abstract – Certification of advanced, load-bearing structural systems, such as the newly designed aircraft and automobile composite structures is conventionally performed through extensive physical testing of the materials, components, sub-assembly, and full-scale prototypes. Consequently, these product development processes are both time-consuming and very costly. In this respect, a modeling and simulation framework exploiting the finite element method is being considered for the product design approval and certification program. However, the complexity of the physical system in terms of both the geometry and material responses often raises valid concerns about the credibility of the numerical simulation results. These concerns cover the aspects of simulation Verification, Validation, and Uncertainty Quantification (VVUQ). This talk will provide some insights into the requirements, analyses, and challenges in implementing the simulation VVUQ processes for quantifying and building credibility in predictive computational models. Challenges in developing verified and validated FE simulation models, particularly at the material screening and selection level will be discussed. A case study material, namely the carbon fiber-reinforced polymer (CFRP) composite laminate will be used for illustrative purposes.
