The mechanism of drag reduction via polymer additives is long debated in the literature. We present results of 3D numerical simulations of the realistic pipe flow where material instabilities develop into turbulence. We observe in the simulations that the addition of the polymer solute suppresses the chaotic turbulent motion, indeed, in accordance with the experimental observations of the phenomenon.
The Multi-Scale Mechanics and Materials by Design Lab at Purdue University is seeking a highly motivated and talented individual to fill a postdoctoral research position in the field of biomimetic fiber-reinforced composites. This position offers a unique opportunity to work closely with Professor Zavattieri and collaborate with leading companies in the composites industry, focusing on a novel application of these materials.
We present a general formalism for the analysis of mechanical lattices with microstructure using the concept of effective dynamic mass. We first revisit a classical case of microstructure being modeled by a spring-interconnected mass-in-mass cell. The frequency-dependent effective dynamic mass of the cell is the sum of a static mass and of an added mass, in analogy to that of a swimmer in a fluid. The effective dynamic mass is derived using three different methods: momentum equivalence, dynamic condensation, and action equivalence.

Multiple postdoc and one PhD positions are open at Tsinghua University. The research will take place at Tsinghua University’s Shenzhen International Graduate School (SIGS), located in Shenzhen, China, and is partly sponsored by NSFC and Tsinghua SIGS’s scientific research startup funds.
Multiscale.Sim 2022R2 version is now available globally.
Multiscale.Sim is an add-in tool for the Ansys Workbench environment (it's also compatible with Ansys Mechanical APDL). It can help to predict materials behavior using virtual material testing without having to rely on costly and time-consuming physical testing all the time. The software includes a templates library to easily create microstructure of materials. It's available in English and Japanese UI.
The Multiscale Modeling of Materials and Machine Learning Laboratory (M4L Lab: https://www.m4l-lab.com/) at Villanova University is looking for two Ph.D. students.

Our group in the Department of Mechanical and Industrial Engineering at New Jersey Institute of Technology (NJIT) is working on a range of problems, involving mechanics and physics of 2D materials, soft materials and biological systems. We employ methods of continuum mechanics, mathematics, statistical physics and atomistic simulations to explore the mechanics of 2D materials, electromechanical coupling in soft materials, as well as physical mechanisms underlying the interface of nanomaterials and biology.
We are accepting applications for a post-doctoral fellow position available in our group at Southern Methodist University located in Dallas, Texas. The fellow will be working closely with Prof. Xin-Lin Gao on projects in the areas of solid mechanics, metamaterials, topological optimization, and additive manufacturing. The initial appointment will be for one year, and the position is available immediately.
