A Smooth Finite Element Method Via Triangular B-Splines
(2013-07-25)A triangular B-spline (DMS-spline)-based finite element method (TBS-FEM) is proposed along with possible enrichment through discontinuous Galerkin, continuous-discontinuous Galerkin finite element (CDGFE) and stabilization ... -
Smooth Finite Element Methods with Polynomial Reproducing Shape Functions
(2018-04-03)A couple of discretization schemes, based on an FE-like tessellation of the domain and polynomial reproducing, globally smooth shape functions, are considered and numerically explored to a limited extent. The first one ... -

(2013-05-20)Crystallographic texture in polycrystalline materials are known to play an important role in tailoring suitable properties for various technological applications. In addition, the evolution of texture provides a profound ... -
Some Experimental and Numerical Studies on Evaluation of Adhesive Bond Integrity of Composites Lap Shear Joints
(2018-03-02)Adhesive bonding which has been in use for long as a traditional joining method has gained ground in the last couple of decades due to the introduction of advanced composite materials into the aerospace industry. Bonded ... -
Some Mechanical Properties of Ti-6Al-4V-B Alloys
(2017-09-27)The alloys of Ti are extensively used in a number of industries with the α+β alloy Ti-6Al-4V (referred to as Ti64 hereafter) being the most popular. Recently, it was demonstrated that the addition of a small amount of B ... -
Some Processing and Mechanical Behavior Related Issues in Ti-Ni Based Shape Memory Alloys
(2017-11-30)Shape memory alloys (SMAs) exhibit unique combination of structural and functional properties and hence have a variety of current and potential applications. The mechanical behaviour of SMAs, in particular the influence ... -
Some Studies On Numerical Models For Fracture Of Concrete
(2013-07-02)Concrete has established itself as the most widely used structural material. There is hardly any place where human life and concrete structure do not exist together. It's use is seen in wide variety of structures like ... -

Sound Radiation from Rectangular Panels with Rectangular Cut-out/s
This is largely an analytical investigation and the objective of this study is to compute sound power radiated from rectangular panels that are placed in an infinite baffle (or a rigid wall) and that have rectangular ... -
Space-Time Evolution of the Intraseasonal Variability in the Indian Summer Monsoon and its Association with Extreme Rainfall Events : Observations and GCM Simulations
(2018-03-01)In this thesis, we investigated modes of intraseasonal variability (ISV) observed in the Indian monsoon rainfall and how these modes modulate rainfall over India. We identified a decreasing trend in the intensity of ... -
Space-Time Gauge Theories for Continuum Modelling of Viscoplasticity, Damage And Electro-Magneto-Mechanical Phenomena in Solids
Over the years, sustained research efforts have aimed to understand the material behaviour under a broad range of response regimes, especially from micromechanical or phenomenological perspectives — via both continuum ... -
Space-time variability of near-surface salinity in the Bay of Bengal
Freshwater from monsoon rain and rivers leads to a 5-10 m deep low-salinity layer in the north Bay of Bengal from August to February. The thin fresh layer, with strong stratification at its base, is highly responsive to ...
