Damage detection in cfrp plates by means of numerical modeling of lamb waves ...eSAT Journals
Abstract
The paper presents an application of modeling acoustic waves propagation in a carbon fiber reinforced plastic (CFRP) plates for
damage detection. This task is a part of non-destructive testing (NDT) methods which are very important in many industry
branches. Propagation of Lamb waves is modeled using three-dimensional finite element method by means of commercial
software. In the paper three different cases of plate structures with and without flaws are considered to present review of selected
methods for the detection of defects in time and frequency domain. These are comparisons of: A-scans, B-scans, dispersion
curves, spectrograms, scalograms and energy plots. Developed numerical model first has been validated by means of analytical
solution for isotropic plate.

Everyone’s code has bugs. Luckily there are almost as many tools to help squash bugs as there are bugs to be squashed. In this talk, we’ll take a detailed look at how to debug and fix some common issues associated with WordPress sites.
We’ll explore how Chrome’s Developer Tools can help us pinpoint front end bugs.
Then, we’ll take a look under the hood with the Query Monitor plugin and see what’s going on behind the scenes with your WordPress site, including database queries, included template files, and more.
With all these tools in your toolbox, you can ensure that your code is in the best possible shape and ready to ship!
Create a Workplace People Love – Just add Joyagile42
Keynote presented at agile42 Connect in Berlin, November 2015 – Richard Sheridan is the CEO of Menlo Innovations in Ann Arbor, Michigan.
While his focus has always been around technology, his passion is actually process, teamwork and organizational design, with one inordinately popular goal: the Business Value of Joy!
The talk will explain how it's possible to create an intentional team culture focused on the business value of joy and unleash the human energy and the results you always knew were possible.
Sheridan is an avid reader and historian, and his software design and development team at Menlo Innovations didn't invent a new culture, but copied an old one… Edison's Menlo Park New Jersey lab. Henry Ford's recreation of the Menlo Park Lab in Greenfield Village was a childhood inspiration!
Some call it agile, some call it lean… Sheridan and his team call it joyful. And it produces results, business and otherwise. Six Inc. magazine revenue growth awards, invites to the White House, speaking engagements around the nation, numerous articles and culture awards and so much interest they are doing a tour a day of the Menlo Software Factory™.
Is it possible to introduce an Agile culture in a Bank organization? How to do it?
This is my point of view maturated after a year spent introducing agile in one of the major italian bank
This talk at Italian Agile Day 2015
This talk was part of Wabash College's 2016 visiting lecture series. It addresses how reading and writing changed with the expansion of digital modes of communication in the 20th century, and argues that interdisciplinary training gives students the skills to be successful readers and writers the 21st century.
Industries across the globe are burgeoning. Stiff
competition has permeated every stratum among
enterprises. To sustain themselves in such an environment,
companies are seeking new and improved methods by which
they can revamp their business and also their existing
production processes. With the emphasis firmly resting on the requirement for
more robust processes, companies are transforming their
project plans drastically. Now, the buzz and objective is to
move on to a more adaptive process that ushers in change
and provides results. Moreover, businesses need a process
that offers enhanced flexibility which can alter the very
nature of the process itself.
it merely focuses on all the aspects of online publishing..........at last the process has been very well explained as to how to publish an e book online
Internal combustion engine with oscillating shaft generating higher power, compared to conventional arrangement of pistons and crank gear. It's latest development leads to most essential requirements of an ideal internal combustion engine and special demands that cannot met with a conventional power generator.
