Abaqus CAE is a full modeling and visualization environment for Abaqus products and offers advanced meshing and visualization of Abaqus models and results.
Abaqus Standard provides solutions to implicit finite element analysis, such as static, thermal and dynamics, with robust general contact and nonlinear material modeling options.
Abaqus Explicit is focused on transient dynamics, quasi-static analysis in drop and impact testing, crushing and manufacturing processes.
Automotive vehicles undergo various ranges of road loads according to the driving conditions. Sometimes it experiences unusually large overload such as pot-hole impact or curb strike whose forces are several times of the vehicle weight. Those overloads may induce plastic deformations at some components and these plastic deformations reduce the fatigue life of the components. In some cases, the fatigue crack initiation points may be changed due to the residual stresses which were generated by the overloads. Predicting the fatigue life by general fatigue analysis methodology, which uses linear stress analysis results and linear damage accumulation rule, is very difficult if any component contains residual stresses. This study was performed to assess the effects of overload on the fatigue behavior of automotive suspension components and to develop a fatigue analysis methodology predicting the fatigue life under overload. Fatigue tests were performed for aluminum knuckle with the application of single overload whose magnitude is large enough to generate plastic deformations on the knuckle. The fatigue life of knuckle was reduced and crack initiation points were changed after applying single overload. Those phenomena could not be predicted by adopting linear stress analysis and Minerâ€™s linear damage accumulation rule. By using non-linear stress analysis results and considering residual stress, it was satisfactory to predict the reduction of fatigue life and change of crack initiation points.
Take a look at the amazing and realistic simulation that is practiced by leaders in the automotive, life sciences and medical industries. Simulation is now commonly used to save on prototyping costs by using virtual testing to validate designs. The time savings and reduction in product development costs have created a new way to transform entire business models.
See how these industry leaders are redefining product innovation by using the advanced capabilities in SIMULIA Abaqus to speed time-to-market and improve reliability. Here are just some examples in the SIMULIA Community News:
- BMW moves toward zero-prototyping with detailed crash simulations in the automotive industry.
- GN Resound spans high-tech and life-sciences with topology optimization & drop-testing of hearing aid products.
- SIMULIA Abaqus was used in a young patient’s hip replacement to validate a patient-specific hip design.
The Medtronic Endovascular Therapies R&D group was looking to understand the in-vivo performance and surgical delivery of stent grafts to further optimize device behavior for better patient outcomes.
The engineers at Nabtesco used Abaqus finite element analysis (FEA) software to calculate the contact area and stress of various pinion gear designs. With the help of their own subroutine, the engineers were able to model both contact area and stress history for easier design evaluation. Isight was also utilized for post-processing automation and design optimization.
Isight is a Process Integration and Design Optimization (PIDO) Solution that allows integration of disparate simulation tools without programming for automating simulation process flows. Users can optimize designs with advanced techniques such as Design Of Experiments and six-sigma analysis.
Fast and powerful structural optimization solution based on FEA. Tosca structure can be used early in the design process to determine part shapes for optimized stiffness within a design envelope, or to refine existing designs minimizing peak stresses. Tosca can be coupled with fe-safe, a multi-axial fatigue tool.
fe-safe is a strain-based code for assessing fatigue life seamlessly integrating with leading FEA solvers. fe-safe is based on multi-axial fatigue with metals and rubber capabilities and exclusive implementation of the Verity® Structural Stress Method for welded joints.
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 convergence of SIMULIA and BIOVIA at this year’s “Science in the Age of Experience” event in Boston reflects a deliberate decision on the part of Dassault Systèmes to highlight the profound changes that are coming in the way we all look at the relationships between simulation, design and manufacturing.
