A new formulation of the Phase Field Crystal model is presented that is consistent with the necessary microscopic independence between the phase field, reflecting the broken symmetry of the phase, and both mass density and elastic distortion. Although these quantities are related in equilibrium through a macroscopic equation of state, they are independent variables in the free energy, and can be independently varied in evaluating the dissipation functional that leads to the model governing equations. The equations obtained describe dislocation motion in an elastically stressed solid, and serve as an extension of the equations of plasticity to the Phase Field Crystal setting. Both finite and small deformation theories are considered, and the corresponding kinetic equations for the fields derived.

We are looking for candidates to join the Utah Waves and Architected Materials Group (w.mech.utah.edu). We have fully funded openings for undergrads, MS and PhD. Both full-time and part-time researchers are needed.

I’m enormously pleased that the video of my ⁦iCanX Talk on 15 May 2020 is now placed on YouTube, as well as on https://talks.ican-x.com. Thank Alice ZHANG for creating this wonderland. In preparing the talk, I discovered a new equation: iCanX = ions can do everything. The last slide of the talk lists further readings and watchings, most of which the talk did not cover. The field is full of chaotic energy.

With heart disease being the leading cause of death among adults in the United States, vascular stents are a critical medical device in ensuring patients live longer and healthier lives. There are a variety of stents that range in both size and strength for various applications. Mechanical testing of vascular stent involves testing the vascular stent specimens in various modes of failure including bending, torsion, tensile, crushing, abrasion, and fatigue. This blog post covers certain test types and the recommended equipment to test vascular stents.

Dear Mechanicians,

The James Watt School of Engineering of the University of Glasgow is seeking a highly motivated graduate to undertake an exciting 3.5-year PhD project entitled, ‘multifunctional cellular composites enabled by 3D printing’. The objective of the project is to design additive manufacturing-enabled microarchitected composites with unprecedented properties optimized for location-specific structural and functional requirements for a multitude of applications. Experience and/or a strong interest in one or more of the following areas are essential: Materials science, additive manufac
