This Best Practices document describes major aspects of stent modeling and simulation, familiarizing the reader with its core concepts and best practices. To take full advantage of this Best Practice, you must be familiar with the SIMULIA product Abaqus.
Stents are medical implants for human bodies and represent one of the most notable areas where bio-medical industry has advanced rapidly. This advancement has been possible in part due to the foray of simulation in this area which has largely complemented or replaced the traditional method of developing stents by prototyping and physical evaluation.
Target Audience: Users, Tech Support, Management, and Sales team.
2. Random Vibration Simulation with Abaqus
The concepts associated with performing random vibration simulations are presented in terms of the random response procedure available within the Abaqus finite element simulation software. The paper begins with some general background information on the topic of random vibration. The equations that form the basis for a random response simulation are then presented in matrix notation.
Random response procedures are not supported by the 2017x release of the “Linear Dynamics Scenario Creation” app of the Dassault Systémes 3DEXPERIENCE Platform.
Target Audience: Engineers and Analysts responsible for simulating noise and vibration in mechanical systems.
3. Modeling Crack Propagation with the Extended Finite Element Method (XFEM) in Abaqus/Standard
The Extended Finite Element Method (XFEM) in Abaqus/Standard can be used for modeling the fracture of bulk material by allowing crack initiation and propagation on the interior of finite elements. The following four modeling steps are described in detail:
- · Definition of an enrichment region
- · Definition of an initial crack
- · Definition of a fracture criteria
- · Definition of contact behavior for cracked element surfaces
Target Audience: Engineers and FEA specialists concerned with modeling fracture and failure.
4. Friction Stir Welding Simulation in Abaqus/Explicit
Friction stir welding (FSW) technology involves joining metals without fusion or filler materials. Welded joints are created by the combination of frictional heating and permanent mechanical deformations.
By deploying an Abaqus/Explicit coupled thermal-stress analysis together with the coupled Eulerian-Lagrangian (CEL) formulation, we provide details and guidance for modeling a welded butt joint consisting of a ST4340-C30/AL6061-T6 matrix.
Target Audience: Engineers and Analysts concerned with modeling the advanced joining technology in Abaqus/Explicit.
5. Modeling Techniques in Abaqus for LS-Dyna Material Models
Accurate material modeling is a key to realistic finite element (FE) simulations. Different material models are used for different classes of material, each aiming to capture the correct physical behavior.
This document provides guidance on developing equivalent material modeling techniques in Abaqus for GISSMO and MAT_ARUP_ADHESIVE models in LS-Dyna. These models are popular in the industry but currently not available in Abaqus. GISSMO model is widely used in the automotive industry for crash simulations. This document describes the GISSMO model and its equivalent modeling approach in Abaqus.
Target Audience: FE analysts, LS-Dyna users, Abaqus users
6. Simulation Using the Iterative Solver Technology in Abaqus
This document describes best practices for a new, state-of-the-art iterative linear equation solver in Abaqus/Standard and the 3DEXPERIENCE structural simulation apps.
The new solution capability is based on an original, unpublished proprietary algorithm developed for reliability and efficiency. A scalable parallel implementation results in a very fast, low memory consumption solver well suited for very large models.
The iterative solver is best suited to models with certain characteristics. This Best Practices document provides usage guidelines and strategies to help you best use this technology.
Target Audience: Structural and Mechanical Analysts that develop large computationally intensive finite element models.
7. Using Alternative Strain Measures in a User Material
When implementing (anisotropic) hyperelastic materials (or materials with strain measures alternative to the logarithmic strain) in a user subroutine, it may be necessary to use a different strain in the derivation. However, we must still provide Abaqus with the proper derivative it requires; specifically, the material Jacobian. In this document we show how such a derivative can be obtained.
Target Audience: The users of Abaqus/Standard that develop UMAT subroutines; however, all users of Abaqus with an interest in advanced mechanics will benefit.
8. Powder Compaction Simulation With SIMULIA Abaqus
This Best Practices document describes the key concepts for finite element simulation of the process in which a column of powder is compacted to produce a tablet. The simulation procedure described herein is with SIMULIA Abaqus/Standard, which is a general-purpose finite element (FE) code.
Abaqus has appropriate material models and modeling techniques that can accurately capture evolution of material properties in powder during compaction and can simulate the whole tableting process. This document discusses in detail the material model used to represent the powder and its subsequent compaction along with all the details of finite element model.
Target Audience: Abaqus users, analysts, process engineers.
9. Access Advanced Abaqus Features Using 3DEXPERIENCE SIMULIA Apps
This Best Practices document demonstrates the use of advanced Abaqus features authored by a Mechanical Analyst using the External Solve feature of the Physics Simulation app. The physics simulation is exported as an Abaqus Input file and is updated interactively with additional Abaqus keywords using a simulation process authored in the simulation templates in the Process Composer app. The updated Abaqus Input file is executed using the Compute Orchestration Service. The results are imported back into the 3DEXPERIENCE Physics Results app for postprocessing.
Target Audience: Design Engineers, Mechanical Analysts, CFD Analysts, Methods Developers, and so on.
10. Using Nastran Structural Models in Abaqus
It is not uncommon for analysts to build workflows incorporating multiple software packages. For structural simulations, the capabilities of Abaqus and Nastran can be combined through the use of matrices. In particular, the linear structural models from Nastran may be brought into Abaqus in matrix form for additional linear or non-linear analyses.
This document provides two workflows for translating the Nastran structural models to Abaqus.
Target Audience: Analysts that are generating Abaqus substructures from Nastran matrix data in either OP2 (binary) or DMIG (text) form.
