We use the Stroh formalism to study analytically generalized plane strain deformations of a linear elastic anisotropic layer bonded to a rigid substrate, and indented by a rigid cylindrical indenter. The mixed boundary-value problem is challenging since the a priori unknown deformed indented surface of the layer contacting the rigid cylinder is to be determined as a part of the solution of the ...

A novel instrumentation approach to nanoindentation is described that exhibits improved resolution and depth sensing. The approach is based on a multi-probe scanning probe microscopy (SPM) tool that utilizes tuning-fork based probes for both indentation and depth sensing. Unlike nanoindentation experiments performed with conventional AFM systems using beam-bounce technology, this technique inco...

The development of nanotechnology faces many problems, one of which is lack of a fast and cheap method for fabricating structures whose dimensions are less than 0.1 μm. One method to solve this problem is nanoimprint lithography (NIL). The method of fabricating nanometer scale patterns by NIL was first proposed by Chou1,2 in 1995. Nanoimprint lithography creates patterns by the mechanical defor...

Frictional normal contact probing methods involving instrumented, depth-sensing indentation can be used to estimate the mechanical properties of small-volume structures and materials such as thin films and components of micro-electro-mechanical systems. This paper describes a new method for estimating the plastic properties, i.e. the yield strength and strain hardening exponent, of ductile mate...

Palm leaf character recognition is an area which is at the nascent stage of research. Although character recognition is a well-known application of pattern recognition, lot of work is still to be exploited in handwritten character recognition. The recognition accuracy as per the literature survey for handwritten English characters is very low and for Indian languages it is just started. Researc...

This paper presents the results of an experimental study to evaluate the damage and failure mode of hybrid-fiber engineered cementitious composite (ECC) panels caused by large projectiles or fragments with the aim towards quantifying the extent to which hybrid-fiber ECC improves the resistance of blast panels against impact loading. Drop weight tests are conducted on full-scale blast/shelter pa...

Nanodiamonds, which are the main components of slurry in the precision lapping process of magnetic heads, play an important role in surface quality. This paper studies the mechanistic features of nanodiamond embedment into a Sn plate in the lapping process. This is the first study to develop mathematical models for nanodiamond embedment. Such models can predict the optimum parameters for partic...

In computer programming languages, indentation formats program source code to improve readability. Programming languages make use of indentation to define program structure .Programmers use indentation to understand the structure of their programs to human readers. Especially, indentation is the better way to represent the relationship between control flow constructs such as selection statement...

This study aimed to quantify the biomechanical properties of murine meniscus surface. Atomic forcemicroscopy (AFM)-based nanoindentation was performed on the central region, proximal side of meniscifrom 6to 24-week old male C57BL/6 mice using microspherical tips(RtipE5 mm) in PBS. A unique,linear correlation between indentation depth, D, and response force, F, was found on menis...
