Tension-compression asymmetry
WebThree deformation modes observed during the continuous tension/compression tests were mathematically formulated with simplified relations between the state of deformation and their histories. In terms of the anisotropy and asymmetry of the initial yield stress, the Drucker-Prager's pressure dependent yield surface was modified to include the anisotropy … WebBy considering the same problem in arbitrary dimensions, we find that the physics behind this difference can be traced to the asymmetric propagation of the interaction in the two media. Our results should be relevant to understand the effective potential acting between interfacial proteins in biofilms, and the self-assembly of charged colloids at droplet …

Web2 days ago · The T-C asymmetry is closely correlated to the asymmetry in the critical resolved shear stress (CRSS) of active deformation modes (e.g., dislocation slip and twinning) between tension and compression. In our study, no twins were captured in the current MEA under either dynamic tension or compression even at very high strain rates. Webspirals. First, we simulated the mechanical behavior of a four-module metastructure under tension, compression, rotation, and sliding using the finite-element method. Then, we used 3D printing and mechanical testing to illustrate the tunable anisotropic and asymmetric behavior of spiral-based metastructures in practice.
