    Displacement control ABAQUS

    Good morning, I am doing a bending test on a beam. The beam is loaded with six concentrated loads spaced along the beam. Since the goal is to calculate the ultimate load, the simulation is in displacement control. The displacements of the six load points are made to increase proportionally that...

    SIMULATION PROBLEM

    Thank you very much for your reply, I did the test in displacement control as suggested. A strange thing happens, the curve relating to the simulation in displacement control in addition to showing a lower ultimate load differs much earlier from the simulation in load control. can you justify me...

    SIMULATION PROBLEM

    Thanks Meysam Khodaei, Ok, i try to do the test in displacement control. But I don't understand some things. If the beam were loaded with only one load concentrated in the centerline then ok, I increase the displacement in the centerline and as a force to draw the graph I take the constraint...

    SIMULATION PROBLEM

    Thanks, the concrete is modeled with CDP considering the damage law, the steel through an elasto-plastic relationship (it is always far from the failure tension of the steel), the connecting elements between the steel beam and the concrete slab are springs nonlinear to which an experimental law...

    SIMULATION PROBLEM

    I kindly ask for information about a simulation in ABAQUS with the explicit dynamic approach. I am simulating the bending behavior up to failure of a composite steel concrete beam. The model includes material non-linearities. The goal is to model an experimental test and confirm the collapse...

    ok, I'll try soon. thanks

    ABAQUS EXPLICIT DYNAMIC

    OK thank you very much. I have another question please. In my model there are connectors to which a displacement load law is defined. The analysis consists of various steps and in the displacement output or force output of the connector between the two steps there is a spike/jump. What can this...

    ABAQUS EXPLICIT DYNAMIC

    Hello, I'm running a simulation of a bending test of a particular beam, I have a problem with the analysis time. The analysis used is the explicit dynamic, the test is simulated in about 5 seconds otherwise it would take too long. The kinetic energy is less than the internal one so there should...

    Loading in Abaqus

    You could try to do a displacement control analysis, increasing the displacement in the centerline until a big one (ex. 50cm) and after plot displ-load curve and find what you search.

    Stress in dynamic ABQUS EXPLICIT

    Hi, I am doing a simulation of a composite beam. Concrete is modeled with 2 different law: in compression and tensile laws and damage with CDP, steel with a bilinear elastic plastic relationship. The problem is that I get during the analysis the principal stresses greater than the maximum stress...
