Substantially reduced energy and power capabilities of lithium-ion cell operating at low temperatures pose a technical barrier for market penetration hybrid electric vehicles pure vehicles. The present work delineates Li-ion behaviors by combined experimental modeling approach. An electrochemical-thermal coupled model, incorporating concentration- temperature-dependent transport kinetic properties, is applied validated against 2.2Ah 18650 cylindrical cells over wide range (−20°C to 45°C)...
Johnson-Cook constitutive model is still the most used in metal cutting simulation, although several drawbacks reported literature. A high number of parameters can be found literature for same work material. One question that may arise “What suitable set a given material?”. The present paper puts evidence some issues related with selection these from In this contribution, two sets Ti-6A-4 V are evaluated, using three types models. These models based on different formulations: Lagrangian,...
A set of lithium-ion cells containing a -based positive electrode and graphite negative were cycled nonintrusively at high power (5C rate) elevated temperature . The aged characterized prescribed cycle numbers (up to 5250 cycles) by three-electrode cell, capacity measurement, electrochemical impedance spectroscopy (EIS). Excellent cyclability these under typical hybrid-electric vehicle conditions is demonstrated 18% fade after cycles, the discharge shows mainly parabolic behavior with number...
An innovative concept for a multifunctional structural battery using lithium-ion materials as load bearing elements in sandwich panel construction has been demonstrated. The prototype exhibited an initial capacity of 17.85 Ah, energy density 248 Wh L −1 , specific 102 kg and retention 85.8% after 190 charge–discharge cycles at ~ C/3 rate eight mechanical loading (upto 1060 N). stiffness three-point bend tests follows expectations based on beam theory, proving that the are sharing...
ABSTRACT Reduced order modeling (ROM) is applied to the finite element thermo‐mechanical simulation of metal additive manufacturing at part scale. This a significant challenge because continuously evolving computational domain, on which local reduced basis required apply projection‐based ROM. In this paper, ROM mechanical resolution, much more time‐consuming than thermal one. Considering DED processes (directed energy deposition), it proposed organize training set snapshots according an...
Around 2005, influenza A virus (IAV) once again crossed species barriers and established a stable lineage within canine populations. Currently, avian-origin H3N2 (CIV) is the only strain of that stably circulating in Initially, this was detected exclusively Asian countries, such as China South Korea. However, 2015, it isolated from dogs United States, where subsequently caused large-scale outbreak. Since its initial isolation, CIV has demonstrated ability to infect mammals, including cats....
We apply united-atom (UA) nonequilibrium molecular dynamics simulations to predict the thermal conductivity for amorphous polyethylene at room temperature with chain length (CL) increasing from 4 1260. The is determined by competition of two mechanisms: (1) collision among UA beads and (2) phonon vibration. mechanism mainly dominates CL≤7, while vibration determines CL ≥ 140. between mechanisms 12 ≤ In particular, 8 11 cannot be obtained accurately due aggregation beads.
The thermomechanical analysis of powder-bed fusion using a laser beam is simulated in both meso- and macroscales within framework combining continuum assumption level-set formulation. mesoscale simulation focuses on interaction with the powder bed, subsequent melting solidification. Modelling conducted at scale material deposition, which fusion, hydrodynamics melt pool, thermal stress are simulated. macroscale model part construction post-deposition. During construction, by contrast...
