MIMB Student Paper Competition Winners

Thursday, June 4, 2020

Sponsored by: EMI Modeling Inelasticity & Multiscale Behavior (MIMB) Committee
Chair: Prof. Yong-Rak Kim, Texas A&M University

The MIMB committee's student paper competition was held virtually this year. The competition was chaired by Dr. Yong-Rak Kim (current MIMB technical committee chair) with an ad-hoc committee who served reviews and recommendation of winners. The ad-hoc committee was composed of Dr. Dinesh Katti (North Dakota State University), Dr. Chung Song (University of Nebraska-Lincoln), and Dr. Mohammadreza Yaghoobi (University of Michigan). The committee recommended 5 winners (one first place, one second place, and three equal third place), and the recommendation was approved by the MIMB committee at its meeting held on May 20th, 2020.  Congratulations to all the winners!

Purpose:

  • Increase student involvement in the EMI conference, particularly in the area of modeling of inelasticity and multiscale behavior of materials and structures.
  • Expose students to relevant research from different groups.
  • Facilitate student interactions with faculty and other students to build up strong networking and be ready to take on future responsibilities within the technical community.
  • Improve student's technical writing and presentation skills, as well as promote high‐quality submissions to the flagship journal of the EMI: Journal of Engineering Mechanics. 

The winners and a brief description of each paper are as follows:
