The impact buckling of a laminated composite bar is investigated in case of one of its ends moving due to axial impact compression. The governing equations considering the first- order shear deformation effect are derived by the Hamilton principle and solved by the finite difference method. The critical axial shortness is determined by the B - R cirterion. The given example is used to highlight the influences of initial imperfection, impact velocity, stress wave and coupled stiffness. It is found that the unsymmetrically laminated bar has a quite different dynamic buckling behaviour from that of the symmetrically laminated bar.

The dynamic torsional buckling and post-buckling of elasto-plastic circular cylindrical shell is studied. By the usage of the Bodner-Partom constitutive relation, the present visco-plastic problem is treated as an orthotropic elastic problem. Based on the nonlinear large deflection shell therory, the governing dynamic buckling equation is solved by the Runge-Kutta method, and the critical buckling stress is determined by the B-R criterion. The present paper is mainly focused on the imperfection sensitivity, the strain rate sensitivity, and the dynamic post-buckling characters for the shell loaded dynamically with a constant shear strain rate. Numerical results show that the critical shear stress and imperfection sensitivity will increase with the increase of strain rate. It is found that the elastic buckling stress is more sensitive to imperfection than the visco-plastic buckling. The present research also reveals some dynamic post-buckling characters for the cylindrical shell, and it is shown that the shell will vibrate with the amplitude proportional to the strain rate in elastic buckling but improportional to the strain rate in visco-plastic buckling. An interesting phenomenon is found that when the strain rate is sufficiently high, there is no dynamic visco-plastic buckling occurrence and the shell produces a harmonic oscillation with a very small amplitude.

This paper analyzes the dynamic structure-fluid interaction response of a submerged composite cylindrical shell. Dynamic equations based on the first-order shear deformation theory include the initial stresses and structure-fluid interaction forces due to fluid. The field equation is solved by expanding the velocity potential into series similar to transverse deflection of the cylindrical shell and the structure-fluid interaction force is obtained. The dynamic response is investigated by means of series expansion method. The effects of structure-fluid interaction on dynamic response are discussed.

This paper concerns the dynamic plastic response of a circular plate resting on fluid subjected to a uniformly distributed rectangular load pulse with finite deformation. It is assumed that the fluid is incompressible and inviscous, and the plate is made of rigid-plastic material and simply supported along its edge. By using the method of the Hankel integral transformation, the nonuniform fluid resistance is derived as the plate and the fluid is coupled. Finally, an analytic solution for a circular plate under a medium load is obtained according to the equations of motion of the plate with finite deformation.

Sulfur(S) is an important element for understanding redox processes, ore formation, environmental chemistry, volcanism and climate. Here, we present a method for in situ S concentration measurement by LA-ICP-MS at the50–100 lm length scale using a 213 nm laser ablation set up coupled to a single-collector magnetic sector ICP-MS with high resolution capabilities. Analyses were performed in medium mass resolution(m/Dm = 3000) mode, which allows for the separation of32 S and34S from molecular interferences. S is simultaneously analyzed along with all major and minor elements so that a priori knowledge of an internal standard concentration is not necessary; this allows for in situ bulk analysis of aphyric groundmass in volcanic rocks or other fine-grained samples. The primary limitation in analyzing S by laser ablation was found to be long-term instrumental drift in fractionation of elemental S relative to other elements,presumably due to drift in laser dynamics. A method for correcting for such fractionation over time was *** correcting for such drift, measurements of homogeneous basaltic glasses are reproducible to within 10 % for high concentration samples([500 ppm) and to within 20 % for low concentration samples(\200 ppm). The applicability of the method was demonstrated using natural and synthetic glasses, aphyric lavas, and micro-laminated sediments.
