In a way, Mechanical Engineers are involved in creating the future. They are the driving force behind many of the technologies and industrial processes in our modern world. Mechanical Engineering will be offered to train manpower with quality education in manufacturing, design, automation and thermal sciences. Students will have adequate flexibility to specialize in areas of their choice through selection of electives and project.
The course will be designed to provide students with adequate exposure for hands-on experience in practice and in design. It will lay emphasis on subjects like Flexible Manufacturing Systems, Computer Integrated Manufacturing, Robotics, Tribology, Composites and Laser Materials, Energy Engineering, Finite Element Methods etc to provide them to take up positions in manufacturing, design, energy generation and conservation and R&D.

In this paper, free vibration behavior of thin functionally graded rectangular plates is investigated by using the dynamic stiffness method (DSM). Classical plate theory along with the concept of physical neutral surface of the functionally graded plate is used to formulate the dynamic stiffness matrix. The dynamic stiffness matrix is finally solved by using the Wittrick-Williams algorithm to compute the natural frequencies. DSM frequencies are compared with those available in the literature. Some inaccurate published results are pointed out and possible reasons for these inaccuracies are discussed. Results for several plate parameters are given and the influence of these parameters on natural frequencies of the functionally graded plate is highlighted. The present study shows that the dynamic stiffness method provides very accurate results for vibration analysis of thin functionally graded plates and these results can be used as benchmark solutions for comparison purposes.
One of the main failure modes of the turbine disc is formation of yield zone at bore which leads to burst of the disc. Hence, disc burst is treated as a critical factor while designing the disc. The scope of present work is to carry-out the elastic – plastic analysis and to find the burst margin of a typical model of a gas turbine disc by means of the finite-element technique for different speed of rotation. The additional goal of the analysis is to compare the burst margin of turbine disc having variable thickness and uniform thickness profile of the disc. The burst margin is estimated using area weighted mean hoop stress (AWMHS) approach. For given burst margin greater than 122%, the variable thickness disc provides lower operating speed in comparison to uniform thickness disc. This helps in reducing hoop stress, which is highly desirable in aero-engine.
A three-dimensional elastic-plastic finite element analysis (FEA) is carried out to estimate the rolling contact fatigue (RCF) crack initiation life for varied slip range on the rail arising from operational variations. The wheel load produces Hertzian contact pressure.
Variation in engine traction induces slip variations that evolves thermal load in terms of heat flux. The aperiodic rolling of wheel on rail develops non-proportional multiaxial fatigue loading. Present study combines these effects by translating the wheel load on rail for multiple (twelve) pass in presence of thermal load, contact pressure and traction through a proposed simulation. The temperature dependent Chaboche material model with nonlinear kinematic hardening law is implemented to estimate the stresses and plastic strains governing the multiaxial fatigue condition at the interface. The location of maximum von Mises stress, found at a material point on or a layer below the rail-head, contemplates the fatigue crack initiation site. A coded search algorithm helps to identify the critical plane of crack initiation corresponding to the maximum fatigue parameter (FP). In contrast to available predictions of RCF life considering contact pressure and/or traction or frictional heat in isolation, present study combines all these loads together and provides a more realistic result by numerical simulation.
In this paper, free vibration analysis of rhombic plate with pre-existing central crack has been done using the finite element method. The Mindlin theory of plate has been used in the process of investigation. The following six boundary conditions at the edges of the plate have been considered. They are simply supported at all edges (SSSS), clamped at all edges (CCCC), free at all edges (FFFF), clamped-simply supported (CSSC), clamped-free (CFFC), and clamped-free-simply supported (CSFS). Effects of crack length on natural frequencies of rhombic plate with different skew angles have been studied. It is observed that percentage drop in fundamental frequency due to presence of central crack in the rhombic plate increases with an increase in skew angle for CCCC, SSSS, and CSSC edge conditions at a given crack ratio (non-dimensional crack length). Under the CFFC, CSFS, and FFFF edge conditions, percentage drop in natural frequency of rhombic plate is very small for crack ratio of 0.2 at different skew angles. In case of the CFFC edge condition of the rhombic plate, percentage drop in fundamental frequency is within 0.7% at all skew angles and with all crack ratios considered. Some of the results obtained by the present method have been compared with the published results. Most of the results obtained are novel for rhombic crack plate.
