We present a linear theory of lipid membranes which accommodates the effects of intra-membrane viscosity into the model of deformations. Within the Monge parameterization, a linearized version of the shape equation describing membrane morphology is derived. Admissible boundary conditions are taken from the existing non-linear model but reformulated and adopted to the present framework. We obtain a complete analytical expression illustrating the deformations of lipid membrane subjected to the influences of intra-membrane viscosity.

The National Center for Additive Manufacturing Excellence (NCAME) at Auburn University is announcing for two fully-funded PhD positions in the area of structural integrity of additive manufactured (AM) materials/parts. These students will work under direction of Dr. Shamsaei from Mechanical Engineering Department. These opportunities include;
1- One PhD student is expected to work on experimental and analytical mechanics, additive manufacturing, fatigue testing and modeling, failure analysis, microstructural characterization, and fracture mechanics.
2- The second PhD student will implement computational mechanics to investigate structural integrity of AM parts. The candidate for this position should have background on crystal plasticity and finite element analysis. This candidate is also expected to be familiar with a finite element software including writing subroutines.
If interested, please send your resume and a cover letter, briefly explaining your relevant experience and publications to Dr Vaziri (mzv0045 [at] auburn.edu).
