“…Curved meridians of the failure surface of the model are described by a cubic polynomial and noncircular trace in the deviatoric plane is represented by an ellipse. The model parameters can be easily obtained by fitting the three experimental test results (uniaxial compressive strength, biaxial compressive strength and a high compression test result) and satisfying equality of mean hydrostatic stress, s m , and the mean shear stress, t m , for both compressive and tensile meridians at the hydrostatic axis [7]. The associated flow rule has been employed and the flow vector has been obtained using the equation of the failure surface.…”

The objective of this work is to provide a reliable numerical model using the finite element method (FEM) for the static and dynamic analysis of reinforced concrete (RC) shells. For this purpose two independently computer programs based on plasticity and viscoplasticity theories are developed. The well known degenerated shell element is used for the static analysis up to failure load, while 3D brick elements are used for the dynamic application. The implicit Newmark scheme with predictor and corrector phases is used for time integration of the nonlinear system of equations. Two benchmark examples analyzed by others are solved with the present numerical model and results are compared with those obtained by other authors. The present numerical model is able to reproduce the path failure, collapse loads and failure mechanism within an acceptable level of accuracy.

“…e load-time functions of various types of commercial and military aircrafts including A707-320, A320, Boeing 747, Boeing 767-400, and Phantom F4 were obtained using theoretical, numerical, or experimental methods [5][6][7][8]. Containment capacities to withstand these aircraft loadings were widely studied by researchers using load-time function methods [9][10][11][12]. e decoupled method has limitations in evaluating impact scenarios with complexity, such as striking with incident angles.…”

After the September 11 attack, the resistant capability of containments against aircraft impacts is required to be assessed for newly constructed nuclear power plants (NPPs). In this paper, the crash of a commercial airplane Boeing 767-200ER on the reinforced concrete containment building of an NPP is analyzed using the missile-target interaction method. Two plane models with the same total weight but different fuel distribution are analyzed. The force-time history obtained by FEA (finite element analysis) is compared with the one calculated by the Riera function. In the integral analysis, the mesh sensitivity of the reinforced concrete containment model is studied, and recommendations are provided on the modelling of containment. The impact phenomenon and damage on the containment are investigated through the validated model. The fuel distribution in the aircraft is found to have strong influence on the damage of the containment, which indicates that the load distribution in the transverse direction is critical in the analysis of aircraft impact. The classic load-time function analysis is unable to incorporate this factor and may not be adequate to provide satisfactory results. For this reason, the application of an integral analysis is advantageous in the safety assessment of aircraft impact.
