A general framework for structural fatigue life evaluation under fatigue cyclic loading using limited sensor data is proposed in this paper. First, limited sensor data are measured from various sensors which are preset on the complex structure. Then the strain data at remote spots are used to obtain the strain responses at critical spots by the strain/stress reconstruction method based on empir...

Recent advances in non-contact strain measurement techniques and large-strain constitutive modeling of the Linear Low-Density Polyethylene film used in NASA Superpressure balloons, StratoFilm 420, are combined to provide a novel measurement technique for the tear propagation critical value of the J-integral. Previously these measurements have required complex test configurations and procedures....

The dynamic critical behavior at the paramagnetic-antiferromagnetic (PM-AFM) transition in manganites has recently been studied experimentally [Niermann et al., Phys. Rev. Lett. {\bf 114}, 037204 (2015)]. We extend Hamiltonian of Paper I by incorporating an energy field, and study corresponding Model C dynamics. use renormalization group (RG) approach calculate exponents $z$, $\nu z$ line-width...

We use the cohesive zone failure model to simulate debonding and failure in high strain-rate plane strain deformations of a heat conducting particulate composite comprised of initially circular metallic particulates immersed in a metallic matrix, with the goal of delineating the effect of these failures on the initiation and propagation of adiabatic shear bands (ASBs). Failure is assumed to ens...

background heat is a harmful factor in workplaces that causes physiologic and cognitive changes in workers. objectives the purpose of this study was to investigate the effect of cooling vest on heat strain and reaction time while wearing chemical-biological-nuclear protective clothes. methods twelve male students with mean age of 25 ± 2 and body mass index (bmi) of 23 ± 1.5 were recruited in th...

advanced high strength steels (ahss) have recently attracted great attention because of their superior mechanical properties. a modern group of these steels, known as twinning induced plasticity (twip) steels, shows a unique combination of strength and ductility even at high rates of strain. in order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...

Extruded unplasticised Poly(Vinyl Chloride) (uPVC) pipes are certified using pressurised pipe tests. During these tests the pipes are subjected to a certain temperature and internal pressure, while the time-to-failure, the time at which the internal pressure drops due to rupture or fracture, is measured. These tests are time consuming and are therefore costly. To circumvent these costs a model-...

AIMS We sought to determine the prevalence of overt and subclinical LV dysfunction in patients with critical left anterior descending coronary artery (LAD) stenosis but without a history of myocardial infarction and to compare diagnostic value of routine echocardiographic parameters with myocardial strain analysis for detection of critical LAD stenosis. METHODS AND RESULTS We retrospectively ...
