This paper presents a new non-linear fatigue damage accumulation model based on continuum damage mechanics. The proposed model has been formulated to take into account the damage evolution of material under different loading levels and the effects of loading sequence on fatigue life. In additional, the model has also considered the mean stress in its damage evolution with fewer parameters. Experimental...
The demand of kinematic accuracy is increasing for modern mechanical systems, while elastic deformation will lead to the decline in kinematic accuracy. This paper examines the application of finite element analysis (FEA) method to kinematic error analysis of elastic mechanisms based on Kineto-Elastodynamics model. The simulation of limit state equations of link mechanisms is performed with Back Propogation...
It is very important to implement chaotic-fractal dynamic method in complex quality control processes because the transfer and control of quality characteristics variation of complex products can't be executed due to uncertainty and it's high coupling in the nonlinear quality systems. According to the complex product quality system's characteristics of multi-dimensional, multi-processes, nonlinear,...
In real world, there are many important applications for the secret sharing with the quasi-threshold multipartite access structure. But there was still not a very efficient scheme proposed in the past. In this paper, we combine the multi-secret sharing and the quasi-threshold multipartite access structure, and present an efficient multi-secret sharing scheme with the quasi-threshold multipartite access...
Reliability allocation problems of large systems become easier if the optimization model can be decomposed and solved as a set of smaller, coordinated sub-problems. A hierarchical structure for optimal reliability allocation based on target cascading is proposed in this paper. An example is given to illustrative the method.
