Parametric Analysis of Oscillating Squeeze Film Using a New Dimensionless ParameterBy Muhannad Mustafa Mustafa, Nusrat J. Chhanda, Mahbubur Razzaque
Abstract: A comprehensive mathematical model has been established including a new dimensionless parameter Ω to investigate the effects of surface roughness and permeability of rubber block on leakage flow rate and hydrodynamic force generated in fluid film between annular porous rubber block and oscillating annular rigid block. The modified Reynolds equation, Laplace equation and governing equation for three-parameter viscoelastic model are solved simultaneously to obtain pressure developed in fluid film between …

A New Numerical Method for the Analysis of Stress Concentration in Tension SpecimenBy Muhannad Mustafa, Nusrat J. Chhanda, M. A. Salam Akanda
Abstract: Analyzing the stress concentration in the critical region of a mixed boundary value elastic problem has always been an important area of interest in applied mechanics. In most of the cases, the problems were circumvented using a numerical solution. A numerical approach has been used to solve elastic problems of arbitrary shaped bodies subjected to mixed boundary conditions. The formulation of displacement potential function is used in finite difference method …
