Hierarchical honeycomb auxetic metamaterials
(
Nature Publishing Group
, 2015 , Article)
Most conventional materials expand in transverse directions when they are compressed uniaxially resulting in the familiar positive Poisson’s ratio. Here we develop a new class of two dimensional (2D) metamaterials with ...
Multiple parts process planning in serial–parallel flexible flow lines: part II—solution method based on genetic algorithms with fixed- and variable-length chromosomes
(
Springer London
, 2015 , Article)
Multiple parts process planning (MPPP) is a hard optimization problem that requires the rigor and intensity of metaheuristic-based algorithms such as simulated annealing and genetic algorithms. In this paper, a solution ...
Evaluation of the Mechanical Properties of AA 6063 Processed by Severe Plastic Deformation
(
Springer US
, 2015 , Article)
In this study, the mechanical properties, including surface hardness, tensile strength, fatigue, and fretting fatigue behavior of AA 6063 processed by equal channel angular pressing as the most efficient severe shear plastic ...
