Robustness of XFEM Method for the Simulation of Cracks Propagation in Fracture Mechanics Problems

Abstract

Abstract:In the present paper a numerical sensitivity analysis is presented with the aim to assess the effectiveness of the X-FEM method for fracture mechanics applications. Different test cases have been adopted for the numerical analyses to point out the X-FEM method behavior in 2-D and 3-D elastic and elasto-plastic conditions. Comparisons with a standard ductile damage model have been carried out to highlight the advantages of the XFEM method in terms of mesh size and shape independency when simulating cracks propagation.

Some Aspects of Modern Drones

“…For example, helicopters or light recreational aircraft are subject to simpler and cheaper approval procedures than commercial aviation (Rulkov et al, 2016;Agarwala, 2016;Babayemi, 2016;Catana et al, 2017;Cican et al, 2018Cican et al, , 2019Cican et al, , 2020Deaconu et al, 2020, Deaconu andGusti and Semin, 2016;Mohamed et al, 2016;Wessels and Raad, 2016;Rajput et al, 2016;Rea and Ottaviano, 2016;Zurfi and Zhang, 2016a;Popa et al, 2019;Zheng and Li 2016;Buonomano et al, 2016a;Faizal et al, 2016;Ascione et al, 2016;Elmeddahi et al, 2016;Calise et al, 2016;Morse et al, 2016;Abouobaida, 2016;Rohit and Dixit, 2016;Kazakov et al, 2016;Alwetaishi, 2016;Riccio et al, 2016a;Iqbal, 2016;Hasan and El-Naas, 2016;Al-Hasan and Al-Ghamdi, 2016;Jiang et al, 2016;Sepúlveda, 2016;Martins et al, 2016;Pisello et al, 2016;Jarahi, 2016;Mondal et al, 2016;Mansour, 2016;Al Qadi et al, 2016b;Campo et al, 2016;Sama...…”

Medical Service of Robots

“…Assisted operation brings infinitely more advantages than the disadvantage that the operator block is voluminous and costly. However, apart from the related space, the costs are amortized over time and the satisfaction of the successful operations is great for both the patients and the medical team (Rulkov et al, 2016;Agarwala, 2016;Babayemi, 2016;Gusti and Semin, 2016;Mohamed et al, 2016;Wessels and Raad, 2016;Maraveas et al, 2015;Khalil, 2015;Rhode-Barbarigos et al, 2015;Takeuchi et al, 2015;Li et al, 2015;Vernardos and Gantes, 2015;Bourahla and Blakeborough, 2015;Stavridou et al, 2015;Ong et al, 2015;Dixit and Pal, 2015;Rajput et al, 2016;Rea and Ottaviano, 2016;Zurfi and Zhang, 2016a;2016b;Zheng and Li, 2016;Buonomano et al, 2016a;2016b;Faizal et al, 2016;Ascione et al, 2016;Elmeddahi et al, 2016;Calise et al, 2016;Morse et al, 2016;Abouobaida, 2016;Rohit and Dixit, 2016;Kazakov et al, 2016;Alwetaishi, 2016;Riccio et al, 2016a;2016b;Iqbal, 2016;Hasan and El-Naas, 2016;Al-Hasan and Al-Ghamdi, 2016;Jiang et al, 2016;Sepúlveda, 2016;…”

Dynamic Models for Rigid Memory Mechanisms

“…Maybe just to say that due to his energy crisis (and not just energy, from 1970 until today), the production of cars has increased at an alert pace (but naturally) instead of falling and they have and were marketed and used. The world's energy crisis (in the 1970s) began to rise from around 200 million vehicles worldwide, to about 350 million in 1980 (when the world's energy and global fuel crisis was declared), about 500 million vehicles worldwide and in 1997 the number of worldregistered vehicles exceeded 600 million (Rulkov et al, 2016;Agarwala, 2016;Babayemi, 2016;Gusti and Semin, 2016;Mohamed et al, 2016;Wessels and Raad, 2016;Maraveas et al, 2015;Khalil, 2015;Rhode-Barbarigos et al, 2015;Takeuchi et al, 2015;Li et al, 2015;Vernardos and Gantes, 2015;Bourahla and Blakeborough, 2015;Stavridou et al, 2015;Ong et al, 2015;Dixit and Pal, 2015;Rajput et al, 2016;Rea and Ottaviano, 2016;Zurfi and Zhang, 2016a;2016b;Zheng and Li, 2016;Buonomano et al, 2016a;2016b;Faizal et al, 2016;Cataldo, 2006;Ascione et al, 2016;Elmeddahi et al, 2016;Calise et al, 2016;Morse et al, 2016;Abouobaida, 2016;Rohit and Dixit, 2016;Kazakov et al, 2016;Alwetaishi, 2016;Riccio et al, 2016a;2016b;Iqbal, 2016;…”
