Multi-position progressive stamping is widely used in industrial fields, such as electronic, automobile and appliance, etc. Finite element numerical simulation has been an effective method to analyze the deformation of multi-position progressive stamping, the progressive die with 13 positions for the high strength steel automotive soleplate component part was manufactured based on the FEA simulation results obtained by multi-position multi-operation modeling method, and the corresponding progressive stamping experiments were carried out. The experimental results of the forward deep drawing of position 3 were further compared with the simulation ones, the results conform well to each other.

In order to research on the hot stamping property of high strength steel, the stamping forming of USIBOR1500P is simulated by the nonlinear finite element software Dynaform and Ansys/ls-dyna. The initial data simulated on USIBOR1500P is obtained by the hot tensile test. The simulation results show that the martensite weight percentage and Vickers hardness are in inverse proportion to stamping speed and initial die temperature.

The vault settlement, the horizontal convergence of Fangdoushan tunnel are monitored and measured. The changing curves with time are drawn; while the data of convergence measurement is analyzed with linear regression. The whole constructing process is simulated to analyze based on FLAC3D. The results of comparative analysis of the data from field monitoring and the data from numerical simulation shows that the simulation results accord well with the actual monitoring data, which will furthermore optimize both the design and the scientific construction

The detailed analysis of the tensile properties of the 1/2Y welded joint made of ultra-high strength steel S 960 QC was carried out. The analysis concerned various parts of welded joint and has been carried out with the help of both experiment and numerical simulation. Results were compared with the data measured using the ARAMIS system. The purpose of the analysis was to provide the constitutive relations for detailed analysis of the welded joint by finite element method.

Abstract In this paper the behaviour of both aluminium honeycombs and closed-cell aluminium foams under static loading was investigated. A comparison was conducted between experimental data of foams with various densities and honeycombs with different cell size and cell wall thickness and previous theoretical analysis. In addition, the finite element numerical simulation of honeycomb was carried out. It was found that the numerical simulation results fitted well with the previous theoretical results.

The explicit dynamic finite element theory is applied on the collision of ships with buoys for computer simulation. Using ANSYS/LS-DYNA finite element analysis software, the numerical simulation of the collision between the ton ship and the buoy with different structures and impact points. The collision force, deformation, displacement parameters and the weak impact points of a buoy are obtained. Based on the numerical simulation results, analysis of buoys and structural collision damages in anti-collision features are discussed, and several theoretical sugestions in anti-collision for the design of buoy are provided.

A 7.8m/s vertical drop simulate of a full composite fuselage section was conducted with energy-absorbing floor to evaluate the crashworthiness features of the fuselage section and to predict its dynamic response to dummies in future. The 1.52m diameter fuselage section consists of a high strength upper fuselage frame, one stiff structural floor and an energy-absorbing subfloor constructed of Rohacell foam blocks. The experimental data from literature [6] were analyzed and correlated with predictions from an impact simulation developed using the nonlinear explicit transient dynamic computer code MSC.Dytran. The simulated average acceleration did not exceed 13g, by contrast with experimental results, whose relative error is less than 11%. The numerical simulation results agree with experiments well.
