![]() ![]() He leads the research teams “Damage” and “Physics and Mechanics of Materials” and is an active contributor to the research on the defect induced fatigue process. #Ansys fluent vbm fullYves Nadot is a Full Professor at the National School of Mechanics and Aerotechnics, located at Poitiers Futuroscope. Modelling strategyįigure 1: Modelling strategy: (a) fatigue sample: fatigue limit and critical defect identified, (b) 3D µ-CT image of the gauge section, (c) each porosity is imaged and labeled, (d) the EIE is computed, (e) the DSG criterion is computed for each individual defect, (f) 3D rendering of the criticality of all defects The Methodology is validated through fatigue tests conducted on AlSi10Mg alloy manufactured by selective laser melting. (f) 3D mapping the criticality of each individual defect.(e) modelling the influence of the defect on the fatigue limit through the DSG approach and,.(a, b, c) obtaining a 3D image of defect population from X-ray micro-computed tomography (µ-CT) or process simulation, (d) computing the Equivalent Inertia Ellipse of each individual pore,.A modelling strategy is proposed to evaluate the influence of defect morphology on the fatigue limit of additively manufactured Al alloys by ![]() ![]() In the keynote lecture a summary of the AM specific fatigue process is presented, where the role of surface and subsurface defects is highlighted, since they have a dominant impact by controlling the fatigue properties. The critical technical challenge being the certification of structural performance and reliability, fatigue research is at the forefront of engineering development. This can be attributed to the compatibility of this technology of the characteristic objectives from this sector namely small production values with flexible delivery schedule and lightweighting. Showcase of what has been done are components that power Rimac’s electric hypercar Nevera, fastest accelerating production car in the world.įatigue Design of Additive Layer Manufacturing MaterialsĪdditive layer manufacturing (AM) has been rapidly evolving over the last decade, and more and more industrial application examples are to be seen in the aerospace sector. Simulations department is working on all major Rimac Technology’s projects for major automotive OEMs. He organized and leads the Simulations department, which is responsible for structural, electrical and thermal simulations of different components of electric powertrain. Ivan Krajinović is Head of Simulations at Rimac Technology, Croatia. Multiple benefits of using cloud computations are also going to be discussed.Ģ Computing Platforms for Engineering Simulations 2015 vs 2020, Lee Margetts, University of Manchester, Benchmark, July 2021ĭr. Now, almost two years using cloud solution there are multiple lessons learned from POC, creating custom solution, and putting it in production. Microsoft Azure with UberCloud platform has been selected as preferred vendors. The results, speed and Total Costs of Ownership (TCO) has been compared to Rimac Technology on-premise solution. Initially, during first half of 2021, detailed Proof-of Concept (PoC) was done with several cloud providers. Rimac Technology HPC journey started with utilization of one university HPC cluster, then moved to on-premise HPC cluster and finally having a hybrid solution combining on-premise HPC cluster with a cloud solution. #Ansys fluent vbm softwareTwo leading barriers for on premise HPC cluster are high software and hardware costs, while for a cloud-based solution those are total cost of ownership and data security. There are barriers to uptake, either having on-premise HPC cluster or a cloud solution2. Another way to access HPC computing power is HPC cloud computing. They are either built on-premise within the companies or rented from different government organizations or universities. To successfully perform such task powerful HPC cluster are needed. Virtual prototyping and virtual testing using sophisticated numerical codes is becoming more and more dominant way of doing development. Additionally, physical testing has its limitation, from number of sensors per device under test (DUT) to frequency of testing, which is not limited only by speed and costs of production, but also with the availability of testing facilities. Across multiple industries there exist trend to decrease costs of new product development, mostly by decreasing the investment physical prototyping and testing. Cloud-based Simulations in Rimac TechnologyĬloud computing is one of the ongoing trends in numerical simulations. ![]()
