“…We have compared our OH species measurements with the predictions of three MCH mechanisms (Pitz et al [12], Orme et al [24], and Ranzi [57]) and 11 n-heptane mechanisms (Ranzi [ [66], and Golovitchev [67]) as listed in Table 1. The mechanisms discussed here have been developed and optimized to address particular needs and applications, and have not, in particular, been optimized to accurately simulate OH timehistories.…”

“…Nonlinear analysis and linear elastic analysis of the engineering problems under more general circumstances have to resort to numerical tools 5-18 among which the finite element method FEM appears to be widely used 5-7 . It is well known that low-order finite element models of composite beams experience the so-called "slip locking" phenomenon for large values of the shear connection stiffness [8][9][10] . Possible strategies in finite element analysis to reduce or even to eliminate slip locking are lowering the degree of interpolation functions for the slip or introducing elements with larger numbers of degrees of freedom.…”

Deformation of partially composite beams under distributed loading and free vibrations of partially composite beams under various boundary conditions are examined in this paper. The weak-form quadrature element method, which is characterized by direct evaluation of the integrals involved in the variational description of a problem, is used. One quadrature element is normally sufficient for a partially composite beam regardless of the magnitude of the shear connection stiffness. The number of integration points in a quadrature element is adjustable in accordance with convergence requirement. Results are compared with those of various finite element formulations. It is shown that the weak form quadrature element solution for partially composite beams is free of slip locking, and high computational accuracy is achieved with smaller number of degrees of freedom. Besides, it is found that longitudinal inertia of motion cannot be simply neglected in assessment of dynamic behavior of partially composite beams.
