Define concrete properties beyond the elastic range. Warning: Success in analyzing plain and reinforced concrete problems depends significantly on making sensible choices regarding the concrete material parameters described in this section as well as, in the case of reinforced concrete, the definition of rebar in the problem. It is important to be familiar with the issues relating to concrete ...

If the concrete beam exposed to static loading in the lab at the rate of loading = .05 mm/sec., how to define this rate accurately in ABAQUS?

Abaqus CDP(Concrete Damaged Plasticity) model can replicate the failure, given that you define the properties of concrete correctly. The convergence problems do exist in static general analysis ...

Such as with reinforced concrete where the volume fraction of the rebar is between 1% and 4%). We can define as many different combinations and orientations of rebar layers as are needed within a single element. They have material properties that are distinct from those of the underlying or host element. Defining rebar layers in Abaqus/CAE

The concrete damage plasticity model can be an effective model to simulate the concrete inelastic behavior under cyclic loading in the ABAQUS. There is no reasonable way to define the damage ...

I have some questions about how to define boundary conditions for 4 points bending reinforced concrete with Abaqus. So I model this beam but I don't know how to define boundary conditions and step. Can You please help me? The model is 1/4 beam because the beam is symmetrical. In result the Force=0 in all model, I don't know how to solve that .

28-2-2016· This video presents one of the ways of modelling framed reinforced concrete multi-storey structures subjected to earthquakes in the commercial Finite Element program Abaqus.

2 天前· I have edited an ABAQUS input file generated from the maple code written to create a 3D model for analysis. The input file is missing the nodes and element definitions. Can someone give me some example on how to edit the following code to input the model for analysis.

3-7-2018· Concrete is a most important component in building materials. So there are a lot of research and experiments have been done on concrete. This tutorial covers the simulation of reinforced concrete ...

I wrote USDFLD and UEXPAN subroutine and defined field variable in abaqus to decrease modulus of elasticity and compressive and tensile behavior. But when i check the results, i see there is no difference between when i define field for compressive and tensile behavior or not. Abaqus just used USDFLD for decreasing modulus of elasticity.

Define hardening in compression for the concrete damaged plasticity model. This option is used to define the compression hardening data for the concrete damaged plasticity material model. It must be used in conjunction with the CONCRETE DAMAGED PLASTICITY and CONCRETE TENSION STIFFENING options.

This option is used to define compression damage (or stiffness degradation) properties for the concrete damaged plasticity material model. The CONCRETE COMPRESSION DAMAGE option must be used in conjunction with the CONCRETE DAMAGED PLASTICITY, CONCRETE TENSION STIFFENING, and CONCRETE COMPRESSION HARDENING options.

From the menu bar in the Edit Material dialog box, select Mechanical Plasticity Concrete Damaged Plasticity. (For information on displaying the Edit Material dialog box, see Creating or editing a material.). Click the Plasticity tab, if necessary, to display the Plasticity tabbed page.. Toggle on Use temperature-dependent data to define data that depend on temperature.

The input file consists of a series of lines containing ABAQUS options (keyword lines) and data (data lines). The input syntax for keyword and data lines is described in “Input syntax rules,” Section 1.2.1. Most input files have the same basic structure. The following portions of the input file are specified to define a finite element model:

I found in the help of Abaqus that I can use the "Bolt load" option to define the pre-tension, but it does not work for my model. Because my model doesn't have surface to choose for this type of load (it's a 2D wire part). Would you please let me know how can I define this pre-tension (or pre-strain) in my model? Thank you in advance, »

In this blog, I want to discuss units in Abaqus. On one hand, I can be short on it: we can choose what we like, as long as it is consistent. On the other hand, the Unit system in Abaqus is a common source of mistakes. Therefore I want to go into a bit more detail. Read more here.

24-3-2009· I am newcomer in abaqus, I spent 2 weeks to read documentation but I can not image how can I define a material model like Newton-Hoff or Swiff. Abaqus is so differrent with other fem sofware about defining material model. For Plastic behaviour, it only show a table with Yield stress and strain.

Every engineer trying to solve non-linear finite element analyses has experienced it: convergence difficulties. In this blog I will give ideas for finding the cause of the convergence issues, as well as some common solutions in Abaqus FEA.. 1) Check the job diagnostics.

Hi Farhad, The interaction between steel and concrete can be modelled in two ways but they are essentially the same, contact being more convenient: 1. Using cohesive element at the interface and defining the traction separation relationship between the two. 2. Using Cohesive Contact between the two interacting surfaces and here also defining the traction separation relationship between the two ...
