Effect of Cyclic Strain Path And Vibration Cycles on Shear Modulus And Damping of Sand
(2017-09-23)The soil strata is often subjected to various kinds of vibrations such as that caused by earthquakes, water waves, traffic loads, wind power plants, construction related equipments, pile driving and vibratory machines. The ... -
The Effect Of Interference Of Strip Foundations And Anchors On Their Ultimate Bearing Capacity And Elastic Settlement
(2011-01-10)Due to close proximity of different civil engineering structures, the ultimate bearing capacity and failure pattern of adjoining footings/anchors are often influenced by their mutual interference. The present thesis is an ... -
Effect of Particle Shape on the Mechanical Behaviour of Granular Media : Discrete Element Simulations
(2018-03-08)Granular materials are characterized by its discrete nature which makes their behaviour very complex to understand when subjected to various loading situations. Comparing other materials, the understanding of granular ... -
Effect of pre-rotation on cavitation in centrifugal and mixed flow pumps.
It has been theoretically shown that introduction of prerotation at the impeller inlet at design point improves the cavitation performance. A qualitative assessment of this from existing data on centrifugal pump impellers ... -
Effect of viscocity and surface tension on the taylor instability of the surface of a cavitation bubble
This thesis is devoted to a consideration of the following problem: A spherical mass of fluid of density ??, viscosity ?? and external radius R is surrounded by a fluid of density ?? and viscosity ??. The fluids are ... -
Effects of 3d Morphological Characteristics of Sand on Multi-scale Intergranular and Sand-geosynthetic Interactions
To understand the process of mobilization of shear strength in sands and sand-geosynthetic interfaces at a fundamental level, it is essential to precisely characterize the size and shape of the grains and the shear-induced ... -
Effects Of Reinforcement Parameters On The Behavior Of Geosynthetic Reinforced Foundation Beds
(2010-09-22)Use of geosynthetics for reinforcing soil beds supporting shallow foundations has gained tremendous popularity in recent times. In this thesis, to study and understand the behaviour of geosynthetics reinforced soil ... -
Elastic Wave Propagation and Evaluation of Low Strain Dynamic Properties in Jointed Rocks
(2018-06-05)When the point under consideration is not near to the source of vibration, the strains developed in the rock mass due to the passage of waves are usually of small magnitude, and within the elastic range. However, the rock ... -
