澳洲材料工程本科毕业论文论文题目：Characterization on elastic stress-based structural health monitoring system for pre-stressed engineering structure

Abstract

Material degradation has called more attentions because it decreases the safety, durability, and capacity of structure. Aluminium alloys are considered as the main material tomanufactureaircraft which has great significance for the development of the society. And the localised corrosion of the aluminium structure of the aircraft causes the damage leading to risks of safety and increasing maintain costs. Therefore damage detection is becoming more and more important for the engineering of companies.Structure health monitoring (SHM)which is a new technology can reduce the maintenance costs of the structures by locating and identifying the damages of the structures.

材料降解呼吁更多的关注是因为它的安全性降低，耐久性，和能力结构。铝合金，是制造飞机，为社会的发展具有重大意义的主要材料。和局部腐蚀的飞机铝合金结构造成的损害导致的安全风险和增加维护成本。因此，损伤检测已成为企业的工程越来越重要。结构健康监测（SHM）是一种新技术，可以通过定位和识别结构损伤的减少结构的维修费用。
Thisthesisuses anelastic stress approachformonitoringan aluminiumstructure.In this thesis the application of the ABAQUS 6.12 is carried out for the finite element simulatinganalysis to analyse the healthcharacter of an isotropic aluminium structureby monitoring the behaviour of lamb waves.This thesis aims to use the ABAQUSsoftware which is a finite element model to simulate the SHM model of the aluminium structure. And the Lamb wave is applied in this model because it can stretch a very far area of the structure from onlyone location. The model usespiezoelectric patches including one actuator and one sensor, and the model changes the driving frequencies of Lamb wave to achieve the different responses.
This paper first introduces the background of SHM for prestress engineering structureand it gives a brief introduction of the purpose of the thesis, and the research method of this paper is also illustrated.Then the second part discusses the literature reviews of SHM, and it discusses the previous studies of SHM technology and the pre-stressed engineering structure, and it especially states the characters of piezoelectricity including piezoelectric actuator, piezoelectric sensor and piezoelectric transducer, and then it mainly illustrates the elastic wave including its types and its application in different structures.The third part is the main body of the thesis, the installation and experimental setup in the structure are described, and it builds a damage model to test the structural health using elastic stress approach. Then the results of the research are discussedand some suggestions about the SHMS have also been provided. Finally it comes to the conclusion of the thesis, and it summarizes the main points of the thesis and states the problems of the thesis, and then the recommendations for the further research are stated.The research presents the results of the monitoring of the aluminium structure by proving the distributionsand the classes of the damage identified.Thebenefitofelastic stress approachwillbeshown.It pro本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
