Sometimes you may wish to simulate a process where various parts interact with one another. In such cases it is often impossible to rely on predefined loads and boundary conditions since the exact points of contact are dependent on the solution.

Including contact in your simulation can be a more realistic way to represent loadings.

Abaqus provides a wide range of mechanical models and numerical methods for contact. We will begin this month's webinar with an overview of these capabilities, considering how to select the best options for a given problem.

In this month’s webinar we will be covering residual stress and springback. We will look at their definition and implications on FEA, how to deal with springback efficiently in Abaqus and the transfer of residual stresses and deformed parts between Abaqus steps and solvers.

Often the forming of metallic parts involves large quasi-static deformations and multiple sources of non-linearity. Processes such as these are regularly analysed using Abaqus/Explicit. This has implications when the aim is to model the forming process and determine the final deformed shape of a component.

This blog post, constitutes a continuation of the previous blog post,regarding modeling of steel fibre reinforced-concrete composites with Abaqus. In the current blog post, we will be showing an exemplary steel fibre composite pull out test, in a 3 dimensional model, wherein,also damage of the concrete matrix, is included.This is realised by using the Concrete Damage Plasticity model, available in Abaqus. 

Many material that are used nowadays are composites: they consist of more than one material. To simulate a composite, different approaches can be taken at different length scales.

On the micro scale, a detailed model of all materials with their geometries and interaction can be made. This provides insight into the behavior of the combined material, but it can be difficult to determine boundary conditions that match realistic situations.

The next in the webinar series will cover sequential and fully coupled thermal-stress analyses using Abaqus. 

The three modes of heat transfer, conduction, convection and radiation will be covered, along with how these are defined in CAE.

Frequently a thermal analysis is coupled to a stress analysis in order to determine the impact of thermal loading on the structural behaviour.  If the structural behaviour will not influence the thermal behaviour, a sequential analysis approach can be adopted, but if the thermal behaviour is coupled to the structural behaviour, a fully coupled thermal/stress analysis is required.  This webinar will cover how both forms of analyses are performed.

In this blog post, we will be discussing about steel fibre reinforced concrete (termed as SFRC) and will be showcasing a way (more modelling ways do exist)  to model the interaction between the steel fibre (reinforcement) and the concrete (matrix).

The “Introduction to Non-Linear Analysis Workshop” on the 24th of May, is a free event, held at our location in the Netherlands, for anyone who has some experience of simulation and FEA, but would like to look at extending the scope of the work they do. This workshop is an ideal way to understand what advanced simulation and SIMULIA Abaqus can offer, and find out how easy it actually is to perform a real world non-linear analysis.

In this webinar we will look at some of the characteristics of metal’s inelastic behaviors under monotonic and cyclic loading and how these behaviors can be modelled in Abaqus with the use of inelasticity models. In specific, the bilinear elastic-plastic, kinematic and isotropic hardening plasticity models will be discussed.

Information about the modelling of damage will also be provided for metals experiencing a ductile type of failure.

Geometry is often drawn in 3D, also when it is axisymmetric. The analysis will be much faster when making use of the axisymmetry. In such cases, we need to get an axisymmetric cross-section out of a 3D model. In this blog I will show a way to do this with Abaqus. The main idea is to create a sketch on a cross-section of the part and project the relevant edges to this sketch. This sketch is saved and used to create a new axisymmetric part. This isn't the only way of doing it, but at least it gives an idea.

The “Introduction to Optimization for Abaqus Workshop” is a free event for anyone who has some experience with Abaqus and would like to explore the possibilities of optimization. Both non-parametric topology optimization using Tosca and parametric optimization using Isight are discussed, focusing on the optimization of problems using the finite element code Abaqus.
