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 is an advanced incrementally non-linear constitutive model based on critical state soil mechanics developed specifically for simulation of fine-grained materials.
SANISAND is an advanced elasto-plastic model based on a concept of rotational hardening incorporating the effects of fabric-dilatancy.
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.
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.
Model to represent the behaviour of interfaces based on hypoplasticity. A general approach to model interfaces using continuum constitutive models is adopted.
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.
A high-cycle explicit model for the accumulation of strain in sand due to small cyclic loading. The dependence of the accumulation rate on stress, void ratio, cyclic history and the type of loading is considered. In particular, the ovality and the polarization of the strain path during a cycle are taken into account.
