Erosion by Liquid jet Impingement on Aluminium using plain and cavijets
The impact of materials by liquids occurs under various conditions and is common in a variety of engineering equipment such as hydroturbines, pumps, steam turbine blades, diesel engine liners, spillway gates, ship propellers, ... -
Analysis of volume change behaviour of partly saturated soils.
Classical geotechnical engineering principles have evolved mainly in regions dominated by temperate climates. Over the last few decades, engineering and construction needs have expanded into less familiar areas such as the ... -
Variations in boundary shear stress in sand bed channels subjected to seepage
Field channels are invariably subjected to seepage across the perimeter of their cross sections. Therefore, it is necessary that the effect of seepage be understood clearly, as it may form an important factor to account ... -
Plastic analysis of plates subjected to multiple loads
A simple analysis for the determination of the carrying capacities of the axisymmetric plate under combined loading has been presented in this chapter. Some brief remarks are appropriate on the interpretation to be given ... -
Strength behaviour including stress-strain relations of clays-
Stability problems for their analysis and design necessitate an assessment of appropriate strength parameters of a given soil system. In soil masses, since deformations result largely from slippages between soil particles, ... -
Elastic stress analysis of circular cylinders
When two cylinders of different elastic properties are joined together and the compound cylinder thus formed is subjected to external loading, the stresses at and in the neighborhood of the joint or the interface get ... -
Influences of foundation elasticity on the vibration and buckling characteristics of arches
The effect of foundation deformation has been studied in detail with reference to the buckling of elastically supported and uniformly compressed inextensible circular arches. The numerical results obtained indicate that ... -
Some studies on the ultimate load capacity of arches and arch dams
The behaviour of a plain concrete rectangular section under an eccentric thrust, up to failure, may be studied using an appropriate strain pattern and a suitable stress-strain curve for concrete. The curve obtained using ... -
Studies in the elastic stress analysis of hollow circular cylinders
From the investigations on the analysis of hollow cylinders subjected to axisymmetric boundary conditions reported in the previous five chapters, the following conclusions are summarized: 1) In Chapter 1, an exact solution ... -
Some studies on new types of venturimeters
This thesis presents the details of the investigations on some new types of Venturimeters designed and tested at the Hydraulics Laboratories of the Indian Institute of Science, Bangalore. Chapter I Chapter I gives an ... -
Some studies on the hydraulic jump
An air concentration probe has been developed which is ideally suited for measurements in a jump. Complete air concentration studies of the jump have been made for nine Froude numbers from 2.42 to 11.72. It has been ... -
Probabilistic site characterization and reliability analysis of shallow foundations and slopes
Uncertainty is pervasive in almost every field of engineering, and geotechnical engineering is no exception. Natural soils are heterogeneous and anisotropic in physical properties due to their composition and complex ... -
Vibration of cables under determministic and randon excitations.
Conclusions i) A new method of linear analysis has been developed to handle the non planar free vibration behaviour of cables in the presence of a spatially non uniform lateral load. ii) If the lateral load, even though ... -
Effect of reinforcement parameters on the mechanical behaviour of geosynthetic reinforced sand
Soil possesses very high strength in compression, but virtually no strength in tension. Hence, when used as a construction material in civil engineering applications, soil usually fails in shear. Soil can be reinforced ... -
Bentonite-Kaolinite-sand mixtures as backfill material for nuclear fuel waste disposal vault.
The aim of the present investigation is to find a suitable backfill material to be used in a nuclear fuel waste–disposal vault. The requirements for such backfill material with regard to various characteristics-such as ... -
Ultimate strength and behaviour of reinforced concrete T-beams under combined bending and torsion, Ph.D. Thesis
Summary and Conclusions The various conclusions arrived at in this study are summarized as follows: 1. Equilibrium Method The equilibrium method used in this investigation for the analysis of T beams under combined bending ... -
Stability of slopes and passive earth structures in partially saturated soils by the method of characteristics.
Stability analysis of slopes and passive earth pressures are problems of considerable economic importance and technical interest in geotechnical engineering. Efforts have continuously been made to improve the methods of ... -
Performance analysis and improvent of submersible pumps
The prediction of performance and efficiency of turbomachines based on test results with geometrically similar physical models using scale effect formulae has been done for the past several decades. Now, with the introduction ... -
In-Situ testing of soils and pavement systems using spectralanalysis of surface waves(SASW)
The determination of shear wave velocity profile with depth for any ground or pavement site is essential for: (i) performing earthquake resistant analysis, (ii) carrying out soil liquefaction studies, and (iii) assessing ...
