Ph.D. positions in Mechanical Engineering at University of Connecticut (UCONN)
The lab of Wave Engineering for eXtreme and Intelligent matTEr (We-Xite) has multiple openings for Ph.D. positions. We are looking for exceptional and highly motivated candidates with background in Engineering, Physics, Materials or Mathematics. The research will have a balance between experimental characterizations (non-destructive evaluation of samples fabricated using additive and subtractive methods), numerical simulations (finite element modeling and topology optimization) and analytical derivations (nonlinear dynamics of spring-mass systems).
Effects of solidification defects on nanoscale mechanical properties of rapid directionally solidified Al-Cu Alloy: A large scale molecular dynamics study
Directional solidification of Al-11 at % Cu is investigated by molecular dynamics (MD) simulations utilizing second nearest neighbor modified embedded atom method (2NN-MEAM) interatomic potential. The condition for directional solidification is produced by imposing dissimilar temperatures at the model boundaries along the [1 0 0] solidification direction to create a temperature gradient. During solidification, the solid-liquid front travels through the Al-Cu liquid along the [1 0 0] direction towards the high temperature end.
Faculty Positions in Mechanical Engineering at Boston University
The Boston University Department of Mechanical Engineering anticipates two openings for tenure-track junior faculty positions, pending approval by the Provost. We welcome applications from all Emerging Areas of Mechanical Engineering, including, but not limited to: energy: sustainability and resource management; robotics and control: micro and nanoscale; and advanced materials: smart fabrics and textiles.
Mean stress effect on Gaßner curves interpreted as shifted Wöhler curves
A criterion for the mean stress effect correction in the shift factor approach for variable amplitude life prediction is presented for both smooth and notched specimens. The criterion is applied to the simple idea proposed by the authors in a previous note that Gaßner curves can be interpreted as shifted Wöhler curves. The mean stress correction used has been proposed by Smith, Watson and Topper and, more in general, by Walker.
So Called Timoshenko Beam Theory Should be Called Timoshenko-Ehrenfest Beam Theory
An interesting paper on historical aspects of classical beam theory.
Orientable wrinkles in stretched orthotropic films
Tensional wrinkles are widely observed in elastic thin films, with mono-orientation of wrinkles being usually perpendicular to the stretching direction. Here, by changing material orthotropic direction, we present orientable wrinkles in uniaxially stretched orthotropic membranes. To quantitatively explore orthotropy-related wrinkles and their morphological evolution, we develop a mathematical model by introducing orthotropic, elastic constitution into the extended F\"oppl-von K\'arm\'an nonlinear plate theory that can describe large in-plane anisotropic deformations.
