Modeling and Material property In this paper, three prestressed concrete frame joints were simulated.
Nodes were based on separate material models for steel bar and concrete, which are then combined along with models of the interaction between the two constituents to describe the behavior of the composite reinforced concrete material.

Because phthalates are relatively low molecular weights, high lipophilicity and not chemically bounded to polymers, they are easily released and migrate into foods, beverages and drinking water from the packaging or bottling materials or manufacturing processes.

Axis of the planet given to different materials to comparative simulation and comprehensive analysis, given the best materials of planetary shaft should be selected, improved the reliability of planetary axis under poor conditions.
The selected materials of planetary shaft should be with high yield strength and good rigidity to meet the required strength in severe shock.
Through the analysis of simulation, it won't generate larger influence for the force situation of shell and planetary when the planet shaft materials changed in the prototype model.
