The Effects of Intra-membrane Viscosity on Lipid Membrane Morphology: Complete Analytical Solution

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.

Mechanical behavior of mycelium-based particulate composites

We study the mechanical behavior of mycelium composites reinforced with biodegradable agro-waste particles. In the composite, the mycelium acts as a supportive matrix which binds reinforcing particles within its filamentous network structure. The compressive behavior of mycelium composites is investigated using an integrated experimental and computational approach.

Two Fully-funded PhD Positions in Additive Manufacturing

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@auburn.edu).

Questions About The Relation Between Mindlin's Strain Gradient and Eringen's Nonlocal Linear Elasticity Theories

Here are some definitions which I have in my mind about the hierarchy of field theories of any kind. Please read them and correct me if there is any misunderstanding. Then I shall raise two questions based on this model of thought about the Mindlin's strain gradient and Eringen's nonlocal linear elasticity theories.

Crack Growth Resistance in Metallic Alloys: The Role of Isotropic Versus Kinematic Hardening

We have always modelled crack propagation under monotonic/static loading in metals assuming isotropic hardening. However, we show that anisotropic/kinematic hardening effects play a significant role due to non-proportional straining with crack advance; the isotropic hardening idealization leads to steady state fracture toughness predictions that could be 50% lower. I hope that some of you find this work interesting.

Mechanics of spontaneously formed nanoblisters trapped by transferred 2D crystals

Mechanics of Spontaneously Formed Nanoblisters Trapped by Transferred 2D Crystals. Proceedings of the National Academy of Sciences 2018 - Layered systems of 2D crystals and heterostructures are widely explored for new physics and devices. In many cases, monolayer or few-layer 2D crystals are transferred to a target substrate including other 2D crystals, and nanometer-scale blisters form spontaneously between the 2D crystal and its substrate.
