Quantities such as energy, wall thickness, and corner radius of the tube were observed and measured.
Then, the numerical model was used for calculating the spring-in angle of lots of different laminates in order to evaluate the influence of the thickness, the corner radius and the layup sequence on the laminate deformation.
As seen in Fig. 6, the finite interface thickness smooths the corner of the bubble, thereby reducing the angle calculated by this method.
The influences of the width-thickness ratio and corner perforation of the panel, the stiffening rib size and the cyclic load history are analysed.
The load carrying capacity of the joint is categorized on the base of five parameters: the flange width, the web height, the wall thickness and the corners of the console, and the gap between the WQ-beam endplate and the column face.
For the glass fibre reinforced composite material with a [(±45/0)4/±45]T lay-up this led to the proposal of an optimized geometry: a plane cruciform type specimen with a circular central region of reduced thickness and an adapted corner fillet at the intersection of the arms.
Shallow trench isolation (STI) is the predominating isolation technology for advanced integrated circuits, but the oxide thickness of the convex corner of trenched Si surfaces is thinner than other planar Si surfaces, which causes leakage currents and gate oxide reliability degradation of electrically erasable and programmable read only memory (EEPROM) by the keen convex corner region.
The Wirtz plate is of trapezoidal geometry with a 18 cm base, 1 cm thickness, and a missing corner tip of about 1 cm.
The missing controllable design parameters of the dispenser lever in the design phase included corner rounding, rib thickness, and front lever thickness.
The St . Louis Lambert Airport Terminal(1954), designed by Hellmuth, Yamasaki and Leinweber, has a large hall 36.6 metres (120 feet) square, spanned by four intersecting thin-shell concrete barrel vaults supported at the four corners; the thickness of the shell varies from 20 centimetres (8 inches) at the supports to 11.3 centimetres (4.5 inches) at the centre.
