The convergency of iterative processes can exhibit unexpected behaviours. In this paper an analysis of the convergency of the iterative processes is made through the application of the Newton method to the polynomial equations resolution. This leads to the deenition of a dynamic relaxation scheme applied to computer graphics

This paper addresses the development of the modified adaptive dynamic relaxation (maDR) method. Through a critical review of the merits and disadvantages of previous studies, the primary physical approaches for improving the efficiency of the method are discussed. Emphases are placed on the selection of initial vectors and the calculation of fictitious damping factors. A variety of engineering ...

Strain induced precipitation in HSLA-100 steel was investigated by conducting hotcompression and relaxation tests at temperature range of 850°C to 1100°C and strain rate of 0.001s-1 to 1s-1. The absence of dynamic recrystallization at temperatures below 1000°C was attributedto the influence of dynamic precipitation. The stress relaxation tests showed that strain inducedprecipitation is possible...

Based on the adaptive Dynamic Relaxation (aDR) method, a modified adaptive Dynamic Relaxation (maDR) method is proposed which is more efficient than the former in solving non-linear problems. It is then applied to analysing the elastic-plastic bending of circular plates in large deflection and their following wrinkling, and leads to satisfactory results compared with corresponding experimental ...

This paper presents a new approach for large-deflection analysis of truss structures employing the Dynamic Relaxation method (DR). The typical formulation for DR has been established utilizing the finite difference technique which is categorized as an explicit method. The special characteristic of the explicit method is its simple algebraic relationships in comparison with complicated matrix op...

Branching structure is often used as a supporting of the grid shell due to its geometrical and force-transferring features, rationality shape very important. The “physical” “numerical” hanging models can be for joint form-finding branching free-form shell. However, slack elements may exist in equilibrium model which corresponds inefficient members form-found structure. To solve this problem, me...
