Abstract Ansys software is used to simulate the welding process of boring bar new cylinder head machine. The indirect coupling method analyze temperature field, then stress field and deformation. It found that for double support structure, highest occurs at outer stiffened plate small diameter end, lowest both ends inner structure. deformation whole structure mainly comes from axial deformation...

An analytical investigation is conducted to predict the post-buckling strength of laminated composite stiffened panels under compressive loads. When a stiffened composite panel buckles, the skin would deform into a sinusoidal mode shape, and hence induces additional moments and forces near the skin-stiffener interface region. These induced loads would cause the existing small edge delamination ...

This paper describes a beam scanning antenna loading a movable dielectric plate on a microstrip comb-line antenna. This antenna uses the mechanical system that has the characteristic of an easy structure as well as low costs. The comb, a radiation element, is connected to a microstrip line. The beam direction of the proposed antenna changes according to phase shifts of the microstrip line movin...

Thermoplastic composites offer many opportunities for aeronautics. Among them is the possibility of overmolding composite parts to obtain finished “netshape” in medium series. This paper presents complexity manufacturing method and defects that may occur some grid-stiffened overmolded using aeronautic thermoplastics. The results impact tests up 15 J carried out at various locations plates grid ...

In this paper, transverse and longitudinal vibration of nonlinear plate under exciting of orbiting mass is considered based on first-order shear deformation theory. The nonlinear governing equation of motion are discretized by the finite element method in combination with Newmark’s time integration scheme under von Karman strain-displacement assumptions. For validation of method and formulation...

Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 (PIN–PMN–PT) piezoelectric single-crystal rectangular beams with the PIN:PMN:PT ratio of 0.33:0.35:0.32 are prepared, and their mode-coupling effect is investigated both theoretically and experimentally for ultrasonic array transducer applications. The PIN–PMN–PT rectangular beams become a tall-narrow beam and a short-wide plate, and so exhibiting an unc...
