Methodologies for Assessment of Impact Dynamic Responses
(2017-11-24)
Evaluation of the performance of a product and its components under impact loading is one of the key considerations in design. In order to assess resistance to damage or ability to absorb energy through plastic deformation ...
On The Effect Of Material Uncertainty And Matrix Cracks On Smart Composite Plate
(2017-02-22)
Recent developments show the applications of smart structure in different engineering fields. Smart structures can be used for shape and vibration control, structural health monitoring etc. Smart materials can be integrated ...
A Synergetic Micromechanics Model For Fiber Reinforced Composites
(2014-09-08)
Composite materials show heterogeneity at different length scales. hence concurrent multiscale analysis is the only reliable method to analyze them. But unfortunately there is no concurrent multi-scale strategy that is ...
Two Inverse Problems In Linear Elasticity With Applications To Force-Sensing And Mechanical Characterization
(2013-06-24)
Two inverse problems in elasticity are addressed with motivation from cellular biomechanics. The first application is computation of holding forces on a cell during its manipulation and the second application is estimation ...
Geometric And Material Stability Criteria For Material Models In Hyperelasticity
(2013-07-17)
In the literature, there are various material models proposed so as to model the constitutive behavior of hyperelastic materials for example, St. Venant-Kirchho_ model, Mooney-Rivlin model etc. The stability of such material ...
Mechanics and Mechanisams in Fretting Damage for Stainless Steel and Chromium Carbide Coatings
(2018-04-11)
Fretting is a serious concern in many industrial components, specifically, in nuclear industry for the safe and reliable operation of the component/system. Till date, a lot of efforts has already been made to understand ...
Numerical Studies On Ductile Fracture Of Pressure Sensitive Plastic Solids
(2010-07-08)
Experimental studies have shown that the yield strength of many important engineering materials such as polymers, ceramics and metallic glasses is dependent on hydrostatic stress. In addition, these materials may also ...
Numerical Simulations Of Void Growth In Ductile Single Crystals
(2010-09-03)
The failure mechanism in ductile materials involves void nucleation, their growth and subsequent coalescence to form the fracture surface. The voids are generated due to fracture or debonding of second phase particles or ...
Finite Element And Experimental Studies On Fracture Behavior Of Bulk Metallic Glasses
(2011-01-19)
The objective of this thesis is to study the fracture behavior of bulk metallic glasses. For this purpose, detailed finite element investigation of the mode I and mixed mode (I and II) stationary crack tip fields under ...
