10月31日，来自苏格兰思克莱德大学机械与航空航天工程系的James Boyle教授做客山东大学机械工程学院第89期研究生鼎新论坛，作了题为“Some consequences of stress-range dependent constitutive models in creep”的学术报告。报告由机械工程学院王威强教授主持，机械学院部分老师及研究生参加了本次论坛。

首先，Boyle教授回顾了目前设计上存在的multi-physics simulation，advanced materials modelling，advanced data analysis和design rules等问题，介绍了其在高温环境中对材料模型进行不确定性处理的研究方法，并通过一些简单的材料模型和结构具体描述了不确定性在设计模型处理上的具体应用。接着，Boyle教授重点介绍了不同温度下奥氏体稳态蠕变的数学模型以及在应力范围内的蠕变定律及相关数学模型，利用几个简单的材料模型解释了材料模型的不确定性以及参考应力和骨骼点方法的相关定律。最后，Boyle教授还列举了管道弯头和对称展开环的弹性跟踪研究的例子，让同学们对蠕变规律有了更加深刻的理解。

此次学术交流活动，增进了同学们对材料模型不确定性以及蠕变规律的认识与了解，拓宽了同学们的视野。

主讲人简介：                 

Professor Boyle has been active in Mechanical Engineering research for over 40 years. His main areas of study have been in stress analysis for creep, high temperature design, simplified and robust methods for design, limit and shakedown analysis and the design of pressurised equipment. Research in pressure vessel design has covered design by analysis, the nature and development of design codes, the behaviour of pressurised components at elevated temperature and piping design and analysis. He is the author of over 400 technical papers and reports and several books including conference proceedings, having given over 40 invited keynote lectures worldwide and has been a Visiting Professor in the U.S., Sweden, Japan, Brazil, Russia and Europe.

A particular interest over the past twenty years has been a more modern approach to engineering education, particularly in the large class format for engineering sciences. He has introduced a collaborative, active approach with a novel version of engineering problem solving which institutions have adopted across the UK and beyond. Over 60 invited lectures and workshops on teaching and learning have been given over the past 15 years in numerous institutions in the UK and Europe.
