“…However, the dependence of wavelength w on density and the variations of D and A with density qualitatively differ from those reported in Ref. 3. Furthermore, with the corrected code a progressive buckling mode of deformation is not obtained for density reductions exceeding À0.5%.…”

“…2 and used in the calculations in Ref. 3 did not satisfy plastic normality and (ii) the overall stress-strain curve obtained with corrected code could contain numerically induced high frequency oscillations. 1,4 The error and its consequences are described in detail in Refs.…”

“…3, several material parameters characterizing the uniaxial stress response were taken to vary with the relative density (or equivalently, volume fraction, /): Young's modulus, E, and the reference flow strength, r pl , were taken to increase as the square of the relative density while the densification strain, d , was taken to decrease linearly with the relative density. Here, we show results obtained with the corrected code.…”

Stochastic rate-dependent elasticity and failure of soft fibrous networks

“…[6][7][8][9][10][11][12] From a mechanics perspective, such fibrous networks are exciting micro-architectures that provide avenues to devise efficient functional solutions for a variety of engineering applications. 13,14 The mechanical behavior of biopolymeric networks ensues from the rich dynamics that arise from the properties and topological arrangements of their constituents. They exhibit an initial soft response followed by a rate-dependent nonlinear stiffening that may culminate in a precipitous drop in the overall stiffness beyond a critical strain.…”

Corrugated Paraffin Nanocomposite Films as Large Stroke Thermal Actuators and Self-Activating Thermal Interfaces

“…Next, the CNT forest was compressed vertically using a precision actuator while resting on a hot plate. Upon compression, the CNTs collectively folded, starting at the base of the forest, which resulted in the corrugated morphology shown in Figure , panel D. − The corrugated morphology is visually reminiscent of a macroscopic accordion bellows. Unless otherwise noted below, the CNT forest was compressed to 50% of its as-grown height.…”
