HPRC Seminar on May 1: Toughness, Roughness and Crack Path Engineering for Improved Fracture Resistance

Posted on April 23, 2017 by Jian Tao

Title: Toughness, Roughness and Crack Path Engineering for Improved Fracture Resistance

Speaker:        Dr. Alan Needleman, University Distinguished Professor

                      Professor, Department of Materials Science and Engineering

                      TEES Distinguished Research Professor

                      Texas A&M University

Date: May 1, 2017 2:00-3:00pm

Place: Koldus Building, Room 110

Abstract: I discuss the possibility of engineering crack paths by controlling the features of the microstructure, such as the distribution of second phase particles or the grain morphology, in a manner so as to increase the ductile crack growth resistance of structural metals. The focus is on ductile fracture where crack growth occurs by the nucleation, growth and coalescence of micro-scale voids. Simulations of crack growth in various microstructures are carried out in order to address some basic questions of fracture mechanics. One such question is, do cracks choose a minimum energy path? Another is, what is the relation, if any, between measures of the statistics of fracture surface roughness and the material’s ductile crack growth resistance? The extent to which a material’s crack growth resistance can be significantly increased by suitably designing its microstructure is explored. Perhaps surprisingly, it turns out that, in a range of circumstances, adding defects to a material can increase its fracture resistance. The important role of large-scale simulations in addressing these issues will be illustrated.

Anyone who attends will have an opportunity to win a door prize (tee-shirts and scarfs). Refreshments will be served after the seminar. Please help distribute this message to anyone who may be interested.

I am looking forwarding to seeing you at this seminar on May 1.
