1. Introduction
The Cardiovascular Tissue Mechanics Lab at Emory University has an immediate opening for a postdoc fellow position. Candidates who have a background in solid mechanics including (but not limited to) cardiovascular biomechanics, soft tissue biomechanics, and/or nonlinear solid mechanics are highly encouraged to apply. The position could have a second affiliate appointment at Georgia Tech.
The composite tape-spring hinge (CTSH) is a lightweight structural connector widely employed in space structures, including spacecraft and satellites, due to its high specific strength and stiffness. Introducing cutouts enables CTSH to possess folding and deployment capability, while optimizing the cutouts finely to optimize the performance of CTSH. However, the interaction between cutout size and the dynamic deployment of CTSH is a novel topic.
The ABD matrix is a fundamental method to characterize the overall stiffness behavior of laminated composite structures. Although classical laminate theory has been widely used, it has limitations in predicting the ABD matrix for woven composites. To address this issue, this paper presents a mesoscale homogenization approach aimed at computing the ABD matrix for thin woven composites accurately. The mesoscale representative volume element (RVE) of the woven composite is generated using TexGen and imposed with periodic boundary conditions to enforce the Kirchhoff thin plate assumption.
To address the significant challenges in predicting high-dimensional chaotic systems, this paper introduces a novel hybrid strategy that combines proper orthogonal decomposition (POD), which serves as reduced order modeling (ROM), with next generation reservoir computing (NGRC), a data-driven prediction model. The POD-NGRC strategy harnesses the strengths of POD in extracting principal evolutionary features and reducing system complexity, along with the high accuracy, ease of design, enhanced robustness, and high computational efficiency offered by NGRC.
The International Journal of Solids and Structures is pleased to institute an annual Best Paper Award for Young Investigators. The award will be given annually to a paper published in the previous year whose principal or corresponding author is under the age of 38 or within 10 years of the completion of their PhD.
