Brian Phung recently implemented a flexible numerical framework to simulate arbitrary 3D crack growth in heterogeneous materials. The framework involves adaptive remeshing on a voxel-based geometrical domain. Due to its modularity, the crack representation is de-coupled from the crack-evolution rule and material constitutive model (in the uncracked region), providing significant flexibility to investigate new or existing crack-growth criteria. The work has been published in the March 2019 issue of Engineering Fracture Mechanics. To download the article, click here or contact the MMM Lab. This work is supported by the Air Force Office of Scientific Research (AFOSR) Young Investigator Program Grant No. FA 9550-15-1-0172 and...

Invited talks in Texas and Spain
Prof. Spear recently gave two invited talks: one in Texas and one in Spain. On October 3rd, Spear visited Texas A&M in College Station to give an invited seminar entitled A Multiscale, Multiphysics Modeling Framework to Predict Spatial Variation of Properties in Additive-Manufactured Metals. The work is a collaboration with Prof. Wenda Tan (Utah) and Prof. Tony Rollett (Carnegie Mellon University). MMM Lab member Carl Herriott is leading the research effort. On October 11th, Spear gave an invited talk at the Society of Engineering Science (SES) conference in Madrid, Spain. Her talk was entitled Multiscale Characterization and Modeling of 3D...

US-COMP Website Now Live
The official website for US-COMP — one of two NASA Space Technology Research Institutes — is now live. US-COMP will focus on a Materials Genome Initiative (MGI) approach to accelerate design and deployment of carbon nanotube composites to enable human space missions to Mars. The US-COMP team is led by Prof. Greg Odegard of Michigan Tech and consists of 22 faculty members from 10 different universities, along with partners from AFRL and industry. The team recently met at the University of Utah to hold a kick-off meeting for the 5-year, $15M institute. For more information about the institute and...
