Improving Quality Control Methods to Test Strengthening Technologies: A Multilevel Model of Acoustic Pulse Flow

Abstract

This article describes an approach that makes it possible to substantiate quality control criteria and methods to improve strengthening technologies. The approach was used to test the quality of products made using these technologies and analyze different strengthening methods applied to structural materials. In the experiment, samples of welded joints subjected to various types of strengthening were used that underwent acoustic emission (AE) testing. The results of quick evaluations produced by the proposed multilevel model of acoustic pulse flow were compared with the results of long-term cyclic tests to make a conclusion about the effectiveness of the approach being discussed. To improve strengthening quality control, a method is proposed that can be applied to complex and large-sized structures in the construction industry.

Conceptual Management Framework for Oil and Gas Engineering Project Implementation

“…Technological problems. This group includes such problems as the lack of modern types of equipment and technologies at all stages of the production cycle [13,14,49,62], the high import dependence of oil and gas companies [32,43,63,64], the low level of state technological development as a whole [13,49,65,66], etc.…”

The role of multi-phase metal content in corrosion and premature failure mitigation of steel equipment in oil refiniers. Part 1

“…A premature failure analysis of the steel coils of tubular furnace in oil refinery was carried out after an oil leak occurred, which led to an explosion and therefore to an emergency stop for maintenance and replacement of the damaged coils [8]. The analysis showed that failure is mainly caused by corrosion [13].…”

Influence of 2D graphene nanostructures on the strength characteristics of a composite material

“…Стандартные данные, получаемые по традиционным для полимерного и композиционного материаловедения методикам прочностного исследования (одноосное деформирование), малоинформативны [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Способ, основанный на информационно-кинетическом подходе к диагностированию и многоуровневой модели потока импульсов акустической эмиссии [30,31] может оказаться лучше. Результаты таких исследований необходимы для понимания механизмов разрушения и упрочнения полимерных материалов, оптимизации возможностей их практического применения.…”

“…После этого образцы нагружали на растяжение при комнатной температуре на универсальной разрывной машине Zwick/ Roell Z100 с постоянной скоростью деформирования. Для регистрации сигналов АЭ использовали автоматизированную акустико-эмиссионную диагностическую систему СДАЕ 16(2) [30,31]. Результаты регистрации обрабатывали по многоуровневой модели потока импульсов АЭ.…”
