We present a growth model for special Cosserat rods that allows induced rotation of cross-sections. The law considers two controls, one lengthwise and another rotations. This is explored in greater detail straight with helical hemitropic material symmetries by introduction symmetry-preserving to account the microstructure. example guided-guided rod possessing chiral microstructure considered st...

Understanding the dynamic behavior of domain structures is critical to design and application super-elastic freestanding ferroelectric thin films. Phase-field simulations represent a powerful tool for observing, exploring revealing domain-switching phase transitions in materials at mesoscopic scale. This review summarizes recent theoretical progress regarding phase-field methods films novel buc...

New numerical strategies that reconsider tubing force analysis (TFA) in connection with buckling induced lock-up are presented and applied. The introduce new visualizations of downhole instabilities coiled tubings (CT) for the entire run-in-hole (RIH) process. Most extended reach interventions seek to reduce compressive forces experienced by CT through usage lubrication, vibrations or tractors,...

The mechanics of DNA supercoiling is a subject of crucial importance to uncover the mechanism and kinetics of several enzymes. It is therefore being investigated using several biochemical and biophysical methods including single molecule experimental techniques. An interesting problem within this realm is that of torsional buckling and plectoneme formation in DNA as it is simultaneously put und...

This paper investigates the relationship between mechanical behaviors and shape of corrugated fiberboard by means of buckling analysis, which is done by FEM (Finite Element Method). Firstly, after analyzing the structure of corrugated fiberboard a single-wall corrugated fiberboard model was built. The buckling load was measured in the ideal condition by linear buckling analysis (eigenvalue buck...
