چکیده
Abstract This work presents the development of an explicit/implicit particle finite element method (PFEM) for 2D modeling metal cutting processes. The purpose is to study efficiency implicit and explicit time integration schemes in terms precision, accuracy computing time. formulation marching developed, a detailed on solution steps presented. PFEM remeshing procedures insertion removal particles have been improved model multiple scales and/or space solution. detection treatment rigid tool contact are presented both, schemes. performance studied with set different two-dimensional orthogonal tests AISI 4340 steel at speeds ranging from 1 m/s up 30 m/s. It was shown that if correct selection scheme made, can decrease 40 times. allows us affirm simulations be excessive due used independently meshing process. As practical result, recommendations select given speed given. intended minimize one negative constraints pointed out by industry when using simulators.

متن کاملImplicit–explicit Numerical Schemes for Jump–diffusion Processes
We study the numerical approximation of viscosity solutions for Parabolic Integro-Differential Equations (PIDE). Similar models arise in option pricing, to generalize the Black–Scholes equation, when the processes which generate the underlying stock returns may contain both a continuous part and jumps. Due to the non-local nature of the integral term, unconditionally stable implicit difference ...

Implicit-explicit higher-order time integration schemes for computations of structural dynamics with fluid-structure interaction
In this paper higher order implicit Runge-Kutta schemes are applied to fluid-structure interaction (FSI) simulations. A staggered approach with a structural predictor is applied to an FSI problem. The equations governing the dynamics of the structure are integrated in time by the Explicit Single Diagonal Implicit Runge-Kutta (ESDIRK) schemes and the arbitrary high order finite volume scheme is ...
