An atomistic-continuum multiscale method for modeling the thermomechanical behavior of heterogeneous nanostructures

In this paper, a computational hierarchical multiscale method is presented to investigate the effect of temperature on mechanical behavior of heterogeneous nanomaterials. The embedded-atom method many-body interatomic potential is employed to investigate the complex interaction between the atoms of copper–aluminum (Cu-Al) alloy at various temperature levels. The thermo-mechanical properties of Cu-Al alloy are studied at various percentages of Cu-Al. The Nose-Hoover thermostat is proposed for the molecular dynamics analysis.

Gradient-enhanced statistical analysis of cleavage fracture

I hope some of you will find this work interesting. We present a new Weibull framework for cleavage fracture that incorporates strain gradient plasticity and can estimate the three parameters of Weibull-type models without any prior assumptions. A post-print is available at www.empaneda.com

Controllable Shape Changing and Tristability of Bilayer Composite

The programmable shape transition of a two dimensional sheet to a three-dimensional (3D) structure in response to a variety of external stimuli has recently attracted increasing attention. Among the various shape changing materials, shape memory polymers (SMPs) can fix their temporary shape and/or their length and recover under proper thermal treatment.

A Remotely Controlled Transformable Soft Robot Based on Engineered Cardiac Tissue Construct

Many living organisms undergo conspicuous or abrupt changes in body structure, which is often accompanied by a behavioral change. Inspired by the natural metamorphosis, robotic systems can be designed as reconfigurable to be multifunctional. Here, a tissue-engineered transformable robot is developed, which can be remotely controlled to assume different mechanical structures for switching locomotive function.

PhD Positions Available (up to 2) on Fatigue Resistance of Bone

Bones not only support and protect the various organs of our body but provide structure and enable mobility making them the most important structural materials in the human body. While aging, diet and health are known to significantly affect the structural integrity and fracture resistance of bone, fatigue, a significantly more important loading condition, is rarely studied.

Post-Doctoral Position – Modeling of Thermal Transport in Crystalline Solids

The Materials Theory Group at the School of Materials Engineering of Purdue University has a post-doctoral opening in the area of modeling of thermal transport in crystalline solids.

The unknown paper by M. T. Huber

More often than not I find in the books I read the information about the von Mises yield cirterion without mentioning any contribution of Maksymilian Tytus Huber in this field. E. g. I'm reading now "Materials for Nuclear Plants" by Wolfgang Hoffelner. When discussing the yielding conditions of the material he refers to von Mises, Hencky and even to Maxwell, but does not mention Huber. M. T. Huber anticipated to some extent the criterion of Mises already in 1904 (von Mises published his paper in 1913), but is not recognized by most of mechanicians.

Lüders Bands Phenomenon in ASTM E8 Tensile Testing

Some metals, particularly annealed low-carbon steel, or mild steel, show a discontinuity when transitioning from elastic to plastic deformation that produces the yield point phenomenon in the stress strain curve.
