To clarify the influence of unbalanced coefficient and change in lay-up angle on failure characteristics laminate static aeroelastic problem aircraft, numerical simulations were performed based classical theory Tsai-Wu criterion, as well fluid-structure coupling calculation method. The structure’s stress-strain curves are found to decrease increases. stress curve’s slope is relatively stable, w...

Abstract The following paper presents a novel approach that can be applied to Operational Load Monitoring and Structural Health processes. is based on artificial intelligence (AI) digital image correlation (DIC) techniques. DIC an optical method allows measuring full-field structural displacements strains. In the presented only relatively small fragment of material’s surface monitored by DIC. o...

Following in the recent work of Hurvich and Tsai (1989, 1991, 1993) and Hurvich, Shumway, and Tsai (1990), we propose a corrected variant of AIC developed for the purpose of small-sample state-space model selection. Our variant of AIC utilizes bootstrapping in the state-space framework (Stoffer and Wall (1991)) to provide an estimate of the expected Kullback-Leibler discrepancy between the mode...

The Akaike (1973, 1974) information criterion, AIC, and the corrected Akaike information criterion (Hurvich and Tsai, 1989), AICc, were both designed as estimators of the expected Kullback-Leibler discrepancy between the model generating the data and a tted candidate model. AIC is justiied in a very general framework, and as a result, ooers a crude estimator of the expected discrepancy: one whi...

We numerically analyze transient plane stress deformations of linearly elastic laminates and sandwich structures by using a coupled space–time finite element method with the weak form governing equations derived least-squares method. The are written as seven first-order partial differential in state space formulation, each variable is approximated piece-wise continuous basis functions. sum inte...

An alternative to the set hypothesis for warm-up decrement (WU) is proposed which states that WU is due to the loss over rest of an activity-set consisting of proper adjustment of activation, attention to relevant sources of feedback, etc. Force estimation (Exp. 1) and arm positioning (Exp. 2 and 3) were used as criterion tasks. During an interpolated rest period, activities were introduced whi...

Abstract In the present investigation, laminated composite beams subjected to a bending static loading are studied in order determine their failure mechanisms and first ply (FPF) load. The FPF analysis is performed using refined rectangular plate element. element formulated based on classical lamination theory (CLT) calculate in-plane stresses. To achieve this goal, several criterions, includin...
