This study presents the dynamic and buckling analysis of laminated composite thin arch plate frame structures employing Classical Plate Theory with Finite Element Analysis. For this purpose, effects radius curvature, aspect ratio, stacking order such on first ten natural frequencies, mode shapes, critical load, unstable regions are investigated. Besides, two-bay curved structure is In to perfor...

The Kurdistan Region of Iraq (KRI) forms the northeastern part Arabian Plate that is colliding with Eurasian Plate. Due to ongoing collision, whole KRI territory folded; accordingly, long anticlines are developed in NW – SE trend, they change west wards almost E W. Cretaceous carbonate rocks form bulk anticlines; central KRG. North and northwest wards, Paleozoic, Triassic Jurassic ages exposed ...

We introduce soft folding, a new interactive method for designing and exploring thin-plate forms. A user specifies sharp and soft folds as two-dimensional(2D) curves on a flat sheet, along with the fold magnitude and sharpness of each. Then, based on the soft folds, the system computes the three-dimensional(3D) folded shape. Internally, the system first computes a fold field, which defines loca...

The performance of metal sandwich plates under impulsive blast loads is compared to that of solid plates made of the same material and having the same weight. Three core geometries are considered: pyramidal truss, square honeycomb and folded plate. Plates of infinite length and clamped along their sides are subject to uniform impulsive load. The momentum impulse is applied to the face sheet tow...
