Tube Models for Rubber-Elastic Systems

, 2001
In the first part of the paper we show that the constraining potentials introduced to mimic entanglement effects in Edwards' tube model and Flory's constrained junction model are diagonal in the generalized Rouse modes of the corresponding phantom ...

Estimation of deformation modulus of gravelly soils using dynamic cone penetration tests

Ain Shams Engineering Journal, 2013
Estimating the deformation modulus of gravelly soils is a challenging task. The estimate of deformation modulus of cohessionless soils in general relies on availability of correlation between in situ test parameters and deformation modulus back ...

Evaluating Energy Absorption Performance of Filled Lattice Structures

Advanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...
