Analytical, numerical, and experimental studies of effective elastic properties of periodically perforated materials
Article Abstract:
A study uses an analytical model, finite element analysis and experimental techniques to give the effective elastic properties of a periodically perforated plate under uniaxial tension. Results from the analytical and finite element models of the perforated plate agree with the experimental results using uniaxial testing. The analytical model uses complex variable method and asymptotic homogenization method. A comparison of the different techniques and their limitations are discussed.

Relaxation of peening residual stresses due to cyclic thermo-mechanical overload
Article Abstract:
The purpose of the study is to conduct comprehensive three-dimensional dynamic elasto-plastic finite element analysis of the joint peening treatment and relaxation process. The peening induced residual stresses were examined using a newly developed symmetry cell model capable of describing the characteristics of the processes.

Development and validation of novel FE models for 3D analysis of peening of strain-rate sensitive materials
Article Abstract:
A comprehensive nonlinear dynamic elastic-plastic finite element analysis was conducted to stimulate the shot-peening process. The mechanically induced residual stresses and plastic zone development were examined using a newly developed and more representative symmetry cell.
