RESEARCH ON FATIGUE CRACK PROPAGATION OF LEAF SPRING UNDER VARIABLE AMPLITUDE LOAD
Jixie qiangdu, 2021 The prediction model of leaf springs fatigue crack growth under variable amplitude loads is mainly Schütz phenomenological model. However, the effect of the crack closure effect on fatigue crack propagation and the relationship between the parameters and

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Concatenated Irregular Variable Length Coding and Irregular Unity Rate Coding [PDF]
, 2009 In this contribution we propose the novel serial concatenation of Irregular Variable Length Coding (IrVLC) and Irregular Unity Rate Coding (IrURC), where we matched the corresponding EXtrinsic Information Transfer (EXIT) functions to each other.

Method for identification of sinusoidal signal parameters with variable unknown amplitude
Научно-технический вестник информационных технологий, механики и оптикиA new method proposed for identifying the parameters of sinusoidal signal with unknown variable amplitude. The problem of estimating the parameters of sinusoidal signals is relevant in the problems of dynamic positioning and disturbance compensation, for

Predicting fatigue crack growth under variable amplitude loadings with usage monitoring data
Advances in Mechanical Engineering, 2015 For complex engineering systems, there is an increasing interest in the use of structural health monitoring systems to estimate the current state of damage (diagnosis) and to predict the behavior of the damage in the future (prognosis). For fatigue crack

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Iteratively Decoded Irregular Variable Length Coding and Trellis Coded Modulation
, 2007 In this paper we propose a novel Irregular Variable Length Coding (IrVLC) scheme for near-capacity joint source and channel coding. We employ a number of Variable Length Coding (VLC) component codebooks having different coding rates for encoding ...
