Evolution Of Microstructure

The evolution of microstructure and the mechanical response of ultrapure aluminum subjected to plastic deformation using plate-impact loading was investigated. For the High Purity Aluminum (99.999%), disk sample was shock impacted by a light gun. Observations by transmission electron microscopy reveal that the inside of the early voids consists of nanometer aluminum; it is proposed that they are the result of recrystallization occurring during localization. And some texture may come from the high temperature annealing the secondary grain crystallization behavior and crystallization when the tensile stress effect. This discovery is helpful to the study on the mechanism during the early stage of void nucleation and growth which produced by tensile fracture.

Impact Mechanics

The intervertebral disc (IVD) is often modeled as a biphasic tissue, with both a solid and a fluid phase [1]. While under a constant compressive load, the IVD responds with continuous creep displacement, resulting in the loss of interstitial fluid from the tissue and increased strain on the annular fibers. The mechanical response of the IVD under impact loading conditions has been previously reported by the authors and others. It is unknown, however, how the loss of interstitial fluid affects disc biomechanics under impact loads. In this study, we investigate the effects of creep on IVD impact mechanics.

In order to study the mechanical response of cement concrete pavements under impact loading, four types of typical cement concrete pavement structures are investigated experimentally and numerically under an impact load. Full-scale three-dimensional pavement slots are tested under an impact load and are monitored for the mechanical characteristics including the deflection of the pavement surface layer, the strain distribution at the bottom of the slab, and the plastic damage and cracking under the dynamic impact load. Numerical analysis is performed by developing a three-dimensional finite element model and by utilizing a cement concrete damage model. The results show that the calculation results based on the cement concrete damage model are in reasonable agreement with the experimental results based on the three-dimensional test slot experiment. The peak values of stress and strain as monitored by the sensors are analyzed and compared with the numerical results, indicating that the errors of numerical results from the proposed model are mostly within 10%. The rationality of the finite element model is verified, and the model is expected to be a suitable reference for the analysis and design of cement concrete pavements.

Repeated Impact

A simplified dynamic response model is proposed based on the deformation and dynamic stress response characteristics of soil under impact loading. The foundation is divided into two distinct zones: a projection cylinder acting vertically under impact loading and a hollow cylinder outside the projection area. It is assumed that the ramming deformation of the projected cylinder under the vertical impact load is a quasi-static loading process under the maximum contact dynamic stress through the quasi-static method, and the settlement calculation without lateral deformation is given. It is assumed that the inner wall of the hollow cylinder is subjected to horizontal lateral pressure and the analytical solution of the horizontal dynamic stress considering the plastic deformation of soil is given. The simplified dynamic response model can reflect the mechanical response of soil under impulse train load well which can provide reference for similar projects.
