in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...

INTRODUCTION Parkinsonian syndrome secondary to craniocerebral trauma is a controversial subject. Of the 163 reports of traumatic Parkinsonism which includes over 200 individual cases, only 2% have had sufficient evidence to implicate trauma as the etiological factor." Clinical criteria for the diagnosis of this rare entity include cerebral trauma of sufficient severity to produce midbrain dama...

This paper will analyse two of the likely damage mechanisms present in a paper fibre matrix when placed under controlled stress conditions: fibre/fibre bond failure and fibre failure. The failure process associated with each damage mechanism will be presented in detail focusing on the change in mechanical and acoustic properties of the surrounding fibre structure before and after failure. To re...

For many fracture problems of practical engineering importance, the three-dimensional effects are significant and a three-dimensional analysis for the problems is thus required. In this paper, an endochronic theory coupled with anisotropic damage is first established, which is actually an elasto-plastic damage theory coupled with isotropic-nonlinear kinematic hardening. The ductile damage evolu...

This chapter provides an overview of a series of multiple criteria optimization-based data mining methods, which utilize multiple criteria programming (MCP) to solve data mining problems , and outlines some research challenges and opportunities for the data mining community. To achieve these goals, this chapter first introduces the basic notions and mathematical formulations for multiple criter...

Ground level ozone, airborne particulates (TSP), carbon monoxide, volatile organic compounds (VOCs), nitrogen oxides and sulfur oxides and lead are all regulated and monitored closely by the EPA and are termed "criteria air pollutants." They are considered to be some of the most damaging pollutants because they are so prevalent. Their impacts have been studied extensively, and much benefit cost...

Two alternative software tools for damage identification are presented. The first tool, developed on the basis of the Virtual Distortion Method (VDM), takes advantage of an analytical formulation of the damage identification problem. Consequently, gradient-based optimization method is applied to solve the resulting dynamic inverse problem in time domain. Finite element model of the structure is...

This study was conducted published to investigate there liability of the equation pressure-impulse (PI) reinforced concrete column in previous studies. Equation involves three different levels of damage criteria known as D =0.2, D =0.5 and D =0.8. The damage criteria known as a minor when 0-0.2, 0.2-0.5 is known as moderate damage, high damage known as 0.5-0.8, and 0.81 of the structure is cons...

Peridynamics (PD) is a nonlocal continuum theory based on integro-differential equations without spatial derivatives. The elongation fracture criterion is implicitly incorporated in the PD theory, and fracture is a natural outcome of the simulation. On the other hand, a new fracture criterion based on the crack opening displacement combined with peridynamic (PD-COD) is proposed. When the relati...
