Web10 apr. 2024 · The overall energy functional of dynamic fracture involves the Lagrange function: (11) L = D ( u) − Ψ p o t where u contains the velocity vector and D ( u) is the kinetic energy can be written with material density ρ: (12) D ( u) = 1 2 ∫ Ω u T u ρ d Ω WebYou can probably use a much shorter time period. A period of 0.1s will finish 10x faster than your current step. 0.01 is obviously 100x faster, etc. You just want to check that the kinetic energy (ALLKE) stays significantly lower than the internal energy (ALLIE) so that it can still be considered quasi-static. Web22 feb. 2012 · For a quasi-static analysis the kinetic energy should remain below 5% of internal energy throughout the majority of the analysis. If this is not the case I would remove any mass-scaling and reduce the loading rate by increasing the solution time. Also, the smooth step amplitude should help reduce any fluctuations. jeans m&s
