The wake states resulting from the controlled oscillation of a cylinder transverse to the free stream are presented. A new wake state is revealed by instantaneous measurements of the total and vortex lift phases, and the phase-referenced, quantitative wake structure. This ‘‘intermediate wake state’’ occurs at oscillation frequencies between the previously observed lowand high-frequency states. ...

in this research the quality of walnut kernels under impact loading were studied. due to unavailability of specific varieties of walnut in iran, the tests were carried out on the available genotypes. three different genotypes from walnut orchards of azarshar region were selected and were collected in 2009. a drop test device was designed and constructed to perform the experiments. the impact te...

Tendons primarily experience tensile loading along their fibre-aligned direction. They may at the same time also undergo compression and shear. Some of these complex loadings occur normally, as when a tendon wraps around a bone and is subjected to longitudinal tension and transverse compression. Other complex loadings are abnormal and may lead to rupture, as occurs at the rotator cuff (Józsa an...

The aim of the study was to examine the deformation modes and also degradation of an adhesively bonded rectangular cross section beam used in the automotive body structure. The study included: (1) performing new experimental investigations on the three-point bend behavior of a rectangular cross section beam made by adhesive bonding method. (2) developing a finite element (FE) model to predict t...
