Abstract Although fatigue limits of smooth specimens under various complex loadings have been determined, few models have been proposed to predict well-known experimental results such as size effects and stress gradient effects. This paper addresses the stress gradient effect issue. A new non local multiaxial fatigue approach is proposed

Silicon integrated sensors for thermomechanical stress measurement in very large scale integration (VLSI) has been studied extensively in recent years due to the increasing complexity of modern semiconductor devices. As the chip size has increased continuously to accommodate more functions in modern integrated circuits (IC) technology, the stress ...

Abstract We demonstrate deterministic control of magnetic eigenmodes in ferromagnetic nanobars through engineered stress gradients. By combining finite-element mechanical modeling with micromagnetic simulations, we show how bending-induced strain fields alter both static magnetization configurations and dynamic ...

Abstract Fatigue limit load is one of the most important factors and concerns in designing and manufacturing critical mechanical parts such as crankshafts. Traditionally, this governing parameter is obtained via a time and money-consuming experiment and analysis of a simple structure while it becomes theoretically complicated for sophisticated cases.

Engine piston is one of the most complex components among all automotive. The engine can be called the heart of a car and the piston may be considered the most important part of an engine. In fact, piston has to endure thermo-mechanical cyclic loadings in a wide range of operating conditions. This paper presents high cycle fatigue (HCF) life prediction

Abstract Height above water table in aquatic habitats has long been recognized as the key factor for determining the spatial structure of bryophyte assemblages. Using photosynthetic pigments as indicators of stress along a wet‐to‐dry gradient, I tested whether different habitat preferences were revealed.

Abstract A non-local approach based on continuum damage mechanics is proposed to take into account the stress gradient effect on fatigue crack initiation in fretting fatigue. The concept of subRVE (sub Representative Volume Element) is introduced as a smaller constituent unit of RVE (Representative Volume Element) and with the dimension of material ...
