Prediction of Crack Propagation Through Interfaces and Understanding Joining Methods of Metal Superalloys

Date: Thursday, Apr 27th
Presenter: Dr. Mahabub Alam, School of Mechanical, Industrial, and Manufacturing Engineering, Oregon State University


Advanced materials consist of numerous joints. Understanding joints, their mechanical and fracture behaviour are critical for designing and improving reliability and durability of engineered materials. In this seminar, history of fracture mechanics, implementation of computational methods and their experimental validation in interfacial fracture of composites are discussed with their potential industrial application. Moreover, joining methods of Nickel-based metal superalloys are also briefly discussed with future research plan.

Mahabub Alam received his Ph.D. in Mechanical Engineering from the Oregon State University in September 2016, where he researched on computational and experimental fracture mechanics. After graduation, he worked with the Research and Development of Pacific Light Technologies Inc. as a research contractor till January 2017. Then he joined Oregon State University as a Research Associate with Professor Melissa Santala where he is performing a comparative study comparing different joining methods of Nickel based superalloys such as Inconel 625 and Inconel 740h. His research interest is to deal with real world problems related to mechanics of materials, composites, and joints of materials through modelling and experimenting.
