Parametric study on numerical simulation of missile punching test using concrete damaged plasticity (CDP) model

The problem of damage accumulation in fiber-reinforced concrete to structures supporting underground workings and tunnel linings against dynamic loading is insufficiently studied. The mechanical properties were determined and the mechanism of destruction of fiber-reinforced concrete with different reinforcement parameters is described. The parameters of the Concrete Damaged Plasticity model for fiber-reinforced concrete at different reinforcement properties are based on the results of lab experiments. Numerical simulation of the composite concrete was performed in the Simulia Abaqus software package (Dassault Systemes, Vélizy-Villacoublay, France). Modeling of tunnel lining based on fiber-reinforced concrete was performed under seismic loading.

Annular Fins

In this experiment the single cylinder air cooled engines was assumed to be a set of annular fins mounted on a cylinder. Numerical simulations were carried out to determine the heat transfer characteristics of different fin parameters namely, number of fins, fin thickness at varying air velocities. A cylinder with a single fin mounted on it was tested experimentally. The numerical simulation of the same setup was done using CFD. The results validated with close accuracy with the experimental results. Cylinders with fins of 4 mm and 6 mm thickness were simulated for 1, 3, 4 &6 fin configurations.

Design Construction

Although the reinforcement for openings is checked in accordance with design / construction standard when thinning was observed in T-pipes, this evaluation becomes too conservative or requires much time and effort. This paper describes additional parametric study results and proposes a guideline for thickness management of wall thinning T-pipes. On the other papers related to this project, the experiment and numerical simulation results are reported. This paper referred these results and performed further investigation.

Steel Strength

A systematic parametric study was carried out to investigate the elastic and elastic-plastic buckling behaviors of imperfect steel shell subject to axial compression and internal pressure. Studied parameters include the magnitude of internal pressure, steel strength, and ratio of cylinder radius to shell thickness. Design equations were proposed for calculating the elastic and elastic-plastic buckling strength of imperfect steel shells under combination of axial compression and internal pressure. The buckling strength predicated by proposed equations agrees well with that from the numerical simulation.

This paper is concerned with the response of long, relatively thin-walled tubes bent into the plastic range in the presence of axial tension. The work is motivated by the design needs of pipelines installed and operated in deep offshore waters. The problem is studied through a combination of experiment and analysis. In the experiments, long metal tubes were bent over a smooth, circular, rigid surface (mandrel). Bending of the tubes was achieved by shear and axial end loads. The experimental arrangement is such that a significant section of the test specimen is loaded and deformed in an axially uniform fashion. The ovalization induced in the specimen was measured as a function of the axial load in the tube for two mandrel radii. A two-dimensional numerical simulation of the problem has been developed and validated against the experimental results. This analysis was used to conduct a parametric study of the effect of tension on the ovalization induced in a long tube during bending.
