The U.S. National Committee for TAM is pleased to share its Fall 2019 Newsletter, an annual publication that will be issued each fall. 

In nonlinear elasticity, universal deformations are the deformations that exist for arbitrary strain-energy density functions and suitable tractions at the boundaries. Here, we discuss the equivalent problem for linear elasticity. We characterize the universal displacements of  linear elasticity: those displacement fields that can be maintained by applying boundary tractions in the absence of body forces for any linear elastic solid in a given anisotropy class.

The ability to transform the crystal structure of metals in the solid-state enables tailoring their physical, mechanical, electrical, thermal, and optical properties in unprecedented ways. We demonstrate a martensitic phase transformation from a face-centered-cubic (fcc) structure to a hexagonal-close-packed (hcp) structure that occurs in nanosecond timescale in initially near-defect-free single-crystal silver (Ag) microcubes impacted at supersonic velocities.

The Ira A. Fulton Schools of Engineering (FSE) at Arizona State University (ASU) and the School for Engineering of Matter, Transport and Energy are hiring faculty to support a broad initiative in manufacturing and biomanufacturing. In conjunction with that initiative, we seek applicants for tenure-track/tenured faculty positions in the areas of manufacturing of advanced materials (metals, polymers, ceramics, semiconductor, and composites) and biomanufacturing/biofabrication (biomolecules, biomaterials, cells and tissues).

In "Littlewood's Miscelleny" the celebrated mathematician John E. Littlewood noted that a hoop with an attached mass rolling on a ground plane may exhibit self-induced jumping. Subsequent works showed that his analysis was flawed and revealed paradoxical behavior that can be resolved by incorporating the inertia of the hoop.

A new stickiness criterion for solids having random fractal roughness is derived using Persson's theory with DMT-type adhesion. As expected, we find stickiness, i.e., the possibility to sustain macroscopic tensile pressures or else non-zero contact area without load, is not affected by the truncation of the PSD spectrum of roughness at short wavelengths and can persist up to roughness amplitudes orders of magnitude larger than the range of attractive forces.

Our group at Southern University of Science and Technology (SUSTech) in Shenzhen China is looking for Research Assistant Professors and Postdocs with backgrounds of material science, mechanics, mechanical engineering or related fields.

Our rearch mainly fouces on  4D printing, functional 3D printing, mechanics of soft materials, soft robotics, flexible electronics.

SYMPOSIUM ON SOLID MECHANICS

Symposium Co-Chairs: Dr. Hamid Akbarzadeh and Dr. Dan Romanyk

Call for Papers – Submission Deadline:  January 15, 2020

THE SOLID MECHANICS SYMPOSIUM OF CANADIAN SOCIETY OF MECHANICAL ENGINEERING

Ph.D. research positions are available immediately in the Advanced Materials Research Lab at the University of Miami to perform NSF-funded research in the area of bio-inspired self-healing of cementitious materials. Highly motivated applicants are encouraged to send a CV to Dr. Ali Ghahremaninezhad via email at a.ghahremani@miami.edu.

This project will focus on developing innovative and advanced simulation tools (non-isothermal multi-scale multi-phase flow solver) to manufacture graphene-enhanced polymer composites, which can be used in in EVs with applications in battery cooling systems, battery module housing, and structure of the car body, with improved curing and cooling cycles, reduced time and cost, and tailored thermal-mechanical properties of parts.

Carbon fibre reinforced polymers combines desired features from different worlds. The fibres are stiff and hard, while the polymers are the opposite, weak, soft and with irrelevant fracture toughness. Irrelevant considering the small in-plane deformation that the fibres can handle before they break. It is not totally surprising that one can make composites that display the best properties from each material. Perhaps less obvious or even surprising is that materials and composition can be designed to make the composite properties go beyond what the constituent materials are even near.

A PhD position is available in the Modelling and simulation group in the Department of Mechanical Engineering at the University of British Columbia (UBC), Vancouver, Canada. The position is related to the computational design of lightweight alloys based on high-entropy alloys and metallic materials with nano-architected structure (see sample here).
