The thermal-hydraulics as well as flow-induced vibration of wire-wrapped rod bundles calls for accurate and efficient liquid metal flow simulation and prediction, yet it remains a challenge due to the complex geometries and high Reynolds number flow in wire-wrapped rod channel. Previous efforts towards this goal exclusively adopts full-order modeling (FOM), which is prohibitively computation-intensive.
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.

The MedTrain+ programme will provide excellent experienced researchers with a research, complementary, and transferable skills training experience of the highest international standards.
Dear Colleagues,
I invite you to read our recent publication in the Journal of Physics: Materials: https://iopscience.iop.org/article/10.1088/2515-7639/ace381
Excellent paper looking at temperature profiles during LPBF AM (using miniSLM):
https://www.sciencedirect.com/science/article/pii/S2772369023000312
Of course, questions remain regarding the validity of temperature estimation method, max temp, max cooling rates etc. -
but it is an important step in the right direction!
Hello All,
Gianmarco Manzini (LANL) and I are teaching a short course entitled: "Virtual Element Method in Solid and Fluid Mechanics" at USNCCM17 in Albuquerque, which will be held on Sunday, July 23rd, 2023. If you plan to be at the conference in-person, then do consider attending the short course. A summary of the course follows:

Soft biological tissues often exhibit notable strain stiffening under increasing stretch, and this can have significant effects on tissue growth and morphological development, such as causing symmetry breaking in growing airways and leading to mucosal folding and airway hyperresponsiveness. To investigate the role of strain stiffening and the multifactorial control in growth and remodeling, we consider a growing tubular structure with strain-stiffening effects caused by increased and tightened collagen.
