Dear colleagues, 

Dear Colleague, 

I'm pleased to announce our latest paper on configurational mechanics has just appeared in Acta Mechanica:

Nathaniel N. Goldberg and Oliver M. O’Reilly. A Material Momentum Balance Law for Shells and Plates with Application to Phase Transformations and Adhesion. Acta Mechanica, 2022.

Dear All,

I am excited to share that we recently developed iVABS as an integrated VABS-based framework for design and optimization, parametric studies, uncertainty quantifications of composite rotor blades, and other beam-like structures. This tool is particularly useful for rapid design of composite slender structures with accuracy of detailed 3D FEA at the speed of simple engineering beam theories.

Title: An energy conserving mechanism for temporal metasurfaces

Exceptional points (EP) are non-Hermitian degeneracies where eigenvalues and their corresponding eigenvectors coalesce. Recently, EPs have attracted attention as a means to enhance the responsivity of sensors, through the abrupt resonant detuning occurring in their proximity. In many cases, however, the EP implementation is accompanied by noise enhancement, leading to the degradation of the sensor’s performance.

Special note:

Composite tape-spring hinge (CTSH) is a simple yet elegant mechanical component for various deployable space structures. This paper formulates and addresses cut-out shape optimization of a CTSH, which is seldom touched upon in literature. Both the maximum strain energy stored during the folding process as well as the maximum bending moment during deployment were maximized in a concurrent way, and the multi-objective optimization problem was realized by merging data-driven surrogate modeling and shape optimization.
