Grain Boundary Motion Analysis
08 Aug 2018 | Contributor(s): Jeremy Seiji Marquardt, Xiaorong Cai, Marisol Koslowski
Grain growth is a mechanism to relax residual stresses in thin films. These grains grow out of the thin film surface and are known as whiskers. These whiskers can cause short circuits, so developing scalable and cost effective solutions would increase the reliability and...

Dynamic Failure of Polymer-Bonded Explosives under Periodic Excitation
Presentation Materials | 27 Jul 2017 | Contributor(s): Rachel Katherine Kohler, Camilo Alberto Duarte, Marisol Koslowski
Accidental mishandling of explosive materials leads to thousands of injuries in the US every year. Understanding the mechanisms behind the detonation process is crucial to prevent such accidents. In polymer-bonded explosives (PBX), high-frequency mechanical excitation generates thermal energy and...
Plastic Deformation at the Nanoscale
Online Presentations | 28 Aug 2015 | Contributor(s): Marisol Koslowski
To model the deformation of metallic materials at micron and submicron scales a continuum theory of dislocations is derived. We will introduce the MicroMechanics Simulation Tool and the NanoPlasticity Lab. Both tools are dislocation mechanics simulations for the prediction of plastic deformation...

Plastic Deformation at Micron and Submicron Scales
0.0 out of 5 stars
Online Presentations | 28 Nov 2007 | Contributor(s): Marisol Koslowski
Most people experiences the way objects plastically deform on a macroscopic scale. From a car crash to the bending of a paper clip plastic deformation occurs in the form of a smooth flow as a response of an applied stress. But due to the constant shrinking on the dimensions of mechanical devices...
