Description

[Official Distributor Text]
Today, product simulation is often being performed by engineering groups using niche simulation tools from different vendors to simulate various design attributes. The use of multiple vendor software products creates inefficiencies and increases costs. SIMULIA delivers a scalable suite of unified analysis products that allow all users, regardless of their simulation expertise or domain focus, to collaborate and seamlessly share simulation data and approved methods without loss of information fidelity. The Abaqus Unified FEA product suite offers powerful and complete solutions for both routine and sophisticated engineering problems covering a vast spectrum of industrial applications. In the automotive industry engineering work groups are able to consider full vehicle loads, dynamic vibration, multibody systems, impact/crash, nonlinear static, thermal coupling, and acoustic-structural coupling using a common model data structure and integrated solver technology. Best-in-class companies are taking advantage of Abaqus Unified FEA to consolidate their processes and tools, reduce costs and inefficiencies, and gain a competitive advantage.

Available Constitutive Models

Clay Hypoplasticity (Mašín, 2014)

David Mašín|13.1.2018|Constitutive Models|0 |

Clay hypoplasticity is an advanced incrementally non-linear constitutive model based on critical state soil mechanics developed specifically for simulation of fine-grained materials.

SANISAND (Dafalias and Manzari, 2004)

Yannis Dafalias|13.1.2018|Constitutive Models|0 |

SANISAND is an advanced elasto-plastic model based on a concept of rotational hardening incorporating the effects of fabric-dilatancy.

Sand Hypoplasticity (von Wolffersdorff, 1996)

Peter-Andreas von Wolffersdorff|13.1.2018|Constitutive Models|4 |

Sand hypoplastic model is an advanced incrementally non-linear constitutive model for sand, an outcome of an extensive research at Karlsruhe University in 1990's.

ISA cyclic hypoplasticity (Fuentes et al.)

William Fuentes|27.8.2018|Constitutive Models|0 |

ISA is a mathematical extension of conventional hypoplastic models for soils to improve simulations of cyclic loading. It can be considered as a reformulation of the conventional intergranular strain theory by Niemunis and Herle (1997).

Hypoplastic Interface Model (Stutz et al., 2016)

Hans Henning Stutz|13.1.2018|Constitutive Models|2 |

Model to represent the behaviour of interfaces based on hypoplasticity. A general approach to model interfaces using continuum constitutive models is adopted.

Barodesy (Kolymbas, Medicus, Schneider-Muntau, Fellin)

Dimitrios Kolymbas|22.1.2018|Constitutive Models|0 |

Barodesy is a constitutive model for granular media and does not use standard notations of elasto-plasticity, e.g. yield function, flow rule or plastic potential.

Hypoplastic Model for Thermal Cycles (Ma et al., 2017)

Qijie Ma|2.7.2018|Constitutive Models|0 |

Model to simulate the cumulative feature of volumetric contraction of fine-grained soil subjected to thermal cycles. A thermal stabilization line is introduced to control the stabilized volumetric contraction under thermal cycles.

[Other constitutive models, not present in SoilModels database]
Mohr-Coulomb, Drucker-Prager, Modified Cam-Clay
