“…It was explicit finite element method (FEM) using the commercial FEM tool, ABAQUS/Explicit. This method has been widely used for evaluation of crash or stamping with high speed dynamic material behavior [9][10][11] . Comparisons were made between the result of collision simulations by the FEM tool and their corresponding experimental result and then led to a good agreement in terms of energy absorption and postdeformation between them [9][10][11][12][13] .…”

Article history:This study addresses theissue of safety of the splash guard of a computer numerical control (CNC) machine tool at the design stage. As an impact test for evaluating safety requirements such as strength under the safety regulation is an expensive and iterative task, it is necessary to develop a new method to minimize the task of the impact test for development of the machine tool. In this study, explicit finite element method was adopted forreplacement of the impact test of the splash guard of a machine tool at the design stage. A finite element model was developed for implementing the impact test on an actual vertical CNC lathe and then produced the analysis including plastic strain and deformation to enable the safety of its splash guard to be determined. The analysis results demonstrated that the finite element method can be applied to safety evaluation for design of the splash guard of a CNC machine tool.

“…The material properties are shown in Table 3. The impact is assumed to occur horizontally and is analyzed following an uncoupled procedure in which its effect onto the nuclear power plant is considered through the application of a short-time load (See References [2], [6], [8], [9] and [10]) as shown in Fig. 12.…”

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.

Analysis of aircraft impact is required for newly designed nuclear power plant containments, that are typically robust reinforced concrete (RC) or prestressed concrete structures. In our paper we shortly summarize the main function of containments and show some typical examples for their structural arrangement. From the point of view of the impact we show the typical effects of an aircraft impact and the analysis methods of it. In the second part of the paper a preliminary analysis for aircraft impact into a prestressed concrete containment building is executed with different methods and with a military jet and a large passenger aircraft. At the end results of the analysis are evaluated and suggestions for more detailed modelling are made.
