Article: Interaction of two cylinders immersed in a viscous fluid. On the effect of moderate Keulegan–Carpenter numbers on the fluid forces
This work deals with the hydrodynamic interaction of two parallel circular cylinders, with identical radii, immersed in a viscous fluid initially at rest. One cylinder is stationary while the other one is imposed a harmonic motion with a moderate amplitude of vibration. The direction of motion is parallel to the line joining the centers of the two cylinders. The two dimensional fluid–structure problem is numerically solved by the Arbitrary Lagrangian–Eulerian method implemented in the open-source CFD code TrioCFD.

Disrupting Density-Dependent Property Scaling in Hierarchically Architected Foams
Dear Colleagues,
I invite you to read our latest paper published in ACS Nano: https://pubs.acs.org/doi/10.1021/acsnano.3c01223
A new method of plastic limit analysis for rectangular plates
Based on a new element model of solid body, the plastic limit analysis of plate is carried out. The new element model is a truss composed of 24 bars. Taking the simply supported square plate and rectangular plate under uniform load as an example, by comparing the new element method with the classical plastic limit analysis theory, it can be found that the limit load and the distribution of plastic zone obtained by the two methods are in good agreement.
A new model for elasto-plastic analysis of steel
This is a beautiful, unparalleled elastoplastic model for plastic materials.
Based on the equivalent stress and deformation of regular hexahedron microelement and truss element, a new truss element model is presented. It can be used to solve the elasto-plastic plane stress problem and spatial problem of steel. Through a large number of examples, the new element model can be found to have good accuracy.
A new method of plastic limit analysis for beams and frames
The plastic limit of beams and frames have analyzed by using a new truss element model of solid bodies, compared with the plastic limit analysis method, it can be found that the limit load of the two methods are in good agreement.
