Poroelastic Center of Dilation Revisited
… refer to a singular solution such as the point force, the force dipole, the centers of rotation and dilation, etc. These fundamentals solutions constitute the building blocks for various problems of practical importance and are, therefore, relatively well understood. However, a comparison of the …

Stress evolution during growth and atomic-scale surface structure effects in transition-metal thin films
… for direct extraction and measurement of the force-dipole associated with the adatom-surface interaction.

Dislocations and Green's functions in prestressed solids
… response of an infinite body to a concentrated force. The effect of prestress on dislocation (and inclusion) fields in non-linear elastic solids is analyzed by extending previous solutions by Eshelby and Willis. Employing a plane strain constitutive model (for incompressible incremental …

Three-dimensional kinetic simulations of active suspensions: effect of chemotaxis and steric interaction
… Stokes equation for the flow arising from the force dipole exerted by the particles on the fluid. The fluid flow equations are solved spectrally and the conservation equation is solved by second-order finite differencing in space and second-order Adams-Bashforth time marching. First, the …

Single Cell Force Platforms to Link Force-ECM Coupling in Pathophysiology
… fibrous microenvironment through the action of forces. These dynamic interactions facilitate mechanosensing, critical to fundamental biological processes in pathophysiology. Naturally, the field of mechanobiology has evolved over the past several decades to decipher the role of forces in …

Elongated microswimmers: influence of hydrodynamics
… end or front side of the rod. This generates the force dipole, which these swimming mechanisms exert on the fluid. Using the simulation method of multi-particle collision dynamics (MPCD), we analyze the flow fields of the squirmer rods both in the bulk fluid as well as in the Hele-Shaw geometry, …

Collective dynamics in flowing suspensions of swimming micro-organisms
… In particular, as they swim they exert a force dipole on the fluid; this force induces a disturbance flow in the fluid, the characteristics of which are universal in the far field. This universality allows the development of mean-field theories to describe such suspensions over length …

Elastic interactions of cellular force patterns
Gewebezellen sammeln ständig Informationen über die mechanischen Eigenschaften ihrer Umgebung, indem sie aktiv an dieser ziehen. Diese Kräfte werden an Zell-Matrix-Kontakten übertragen, die als Mechanosensoren fungieren. Jüngste Experimente mit Zellen auf elastischen Substraten zeigen, dass Zellen …
