Non-linearities are included in an incremental fashion. Response is obtained in frequency domain and the effects of any Path-dependent solution in the time domain contrasts with theĮquivalent-linear methods commonly used in earthquake engineering, where The approach utilized by FLAC3D for obtaining a non-linear For aĬomprehensive constitutive law, modulus degradation and variation inĭamping due to changes in strain are inherent to the constitutive law.įor simpler constitutive laws however, use of hysteretic damping and/or Is determined based on the constitutive law used at each zone. The non-linearity and path-dependency of the stress-strain response Versus static is simply a small variation in the solution process. For a dynamic solution, FLAC3D uses real grid-point massesĪnd physically realistic damping. Introduced to facilitate the process of approaching the staticĮquilibrium. For static analysis, additional damping and mass scaling are FLAC3D uses the full equations of motion in its solution Full Non-linear Solution in Time DomainįLAC3D will provide a fully non-linear and path-dependent solution in This page provides a brief overview of some of the features that make FLAC3D ideal for dynamic analysis. Powerful and Easy Preprocessing of Input SignalsĮasy Movie Creation Why Use FLAC3D for Dynamic Analysis?įLAC3D is especially useful for performing dynamic analyses.
