The purpose of this research is to develop a model, with emphasis on compatibility conditions and model building, valid for high cycle fatigue design components such as wind turbines, automobiles, speed railways aeronautical material. In work, we have added the frequency one more variable an existing that already includes maximum stress, stress ratio lifetime. As result, estimation method has b...

In this paper, we show that the Chapman-Kolmogorov formula could be used as a recursive formula for computing the m-step-ahead conditional density of a Markov bilinear model. The stationary marginal probability density function of the model may be approximated by the m-step-ahead conditional density for sufficiently large m.

the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

background:the different duration of delay to first contact with a psychiatrist in depressive disordered patients has been observed in western and non western cultures. this study aimed to examine the duration and predictive factors of delay in contact with a psychiatrist in depressive patients in isfahan city of iran. methods:in this cross sectional study 156 depressive patients were recruited...

This paper presents a magnetostrictive in-pipe impact drive mechanism (IDM). To estimate the output performances of the IDM, a dynamics model was developed based on the magnetostrictive material constitutive model and mechanical model of the IDM. Therefore, an experimental system has been built to test the motion performance of IDM. Simulation and experimental results illustrate that the propos...
