Ductile Mixed-mode Fracture Criterion Development and Crack Growth Simulations




Stable tearing crack growth (slow ductile growth of a macroscopic crack in a load-bearing structure) is an important fracture failure process in ductile materials (e.g. metals) and usually precedes the final catastrophic failure of a structure. In recent years, there has been a growing demand for a simulation-based structural design and evaluation methodology that takes into account the stable tearing crack growth process. Within such a methodology, two too ....etc

MANAGEMENT CONCEPTS and FUNDAMENTALS



WHAT IS MANAGEMENT ?

DEFINITION:

•F.W. Taylor -“Art of knowing what you want to do and
then seeing that it is done the best and cheepest way”.
•Henry Fayol –“To Manage is to forecast, to plan, to
organise, to command, to co-ordinate and to control”.
•Peter F.Drucker –”Management is work and as such it
has its own skills, its own tools and its own techniques”.
•“Management is th ....etc

Fundamentals for the Up-and-Coming Bridge Engineer
Outline
Beam Strength and Deflection
Moment of Inertia
Types of Forces Applied
Young’s Modulus (stress and strain)
Optimization
Beam Deflection
Every object acts as a spring – it will deflect when a force is applied
Extent of deflection depends on force applied, material properties and object shape
Moments of Inertia
A measure of resistance to deflection
A larger moment of inertia means that the beam will be more resistant to deflection
To Increas ....etc

Double-Stator Switched Reluctance Machines (DSSRM): Fundamentals and Magnetic Force Analysis
Abstract
In this paper, a new switched reluctancemachine witha double-stator configuration (DSSRM) is introduced. The proposeddesign is based on optimization of themotional forces, whichleads to a high-grade electromechanical energy conversion process.A local examination of the force densities within and throughouta conventional switched reluctance machine (SRM) shows that themajority of the force produced is in the radial direction and doesno ....etc

Abstract
A nonsmooth (hybrid) 3-D mathematical model ofa snake robot (without wheels) is developed and experimentallyvalidated in this paper. The model is based on the framework ofnonsmooth dynamics and convex analysis that allows us to easilyand systematically incorporate unilateral contact forces (i.e., betweenthe snake robot and the ground surface) and friction forcesbased on Coulomb’s law of dry friction. Conventional numericalsolvers cannot be employed directly due to set-valued force lawsand possible instantaneous velocity chan ....etc

COLOUR FUNDAMENTALS AND COLOUR MODELING


INTRODUCTION
 Color is a powerful descriptor that simplifies object identification and extraction from a scene.
 Characterization of light is central to the science of color.
 Achromatic light is what viewers see on a black and white TV.
 Gray-level is a scalar measure of intensity that ranges from black, to grays, and finally to white.
