Hello everyone, I am trying to simulate the drilling of an aluminum layer by a screw bit. The tool (screw bit) used is of tool steel alloy and is defined as a rigid body. The aluminum layer is defined as the Eulerian workpiece (in order to eliminate element distortion issues). The tool is...

Hello, I have been searching for a subroutine which would help in utilizing the field output variable quantity calculated by ABAQUS/Explicit, surface heat flux (HFL), of one surface elements to be specified as the input for another surface elements. There are two circular workpieces which have...

Hello Everyone! I am facing element distortion issue due to thermal conductance (high magnitude) between aluminum-steel surfaces. The set-up of tool and workpiece is similar to friction stir-spot welding wherein tool is positioned on the top of two layers (aluminum & steel). The tool drills...

Hello, I am trying to drill through a layer which is 1.5 mm thick with the help of a rigid tool which has translational and rotational motion. I have used Johnson-Cook plasticity and failure damage model for the layer. The material for the layer is al-6061. The layer is constrained so that it...

Hello, I am facing difficulty with respect to amplitude definition. My model consists of four steps with different step times in which load and angular velocity are applied and they vary in each step respectively. The load is applied in the form of pressure. My problem in the model is that the...

Hello, I have a question regarding the specification of velocity (feed) using the 'velocity/angular velocity' boundary condition in ABAQUS: if I specify a velocity of 1 m/s without any amplitude and use 'instantaneous' instead, will ABAQUS apply the specified velocity of 1 m/s throughout the...

Hello, I was analysing the history output for different energies and observed that major contributor to 'ETOTAL' i.e. total energy which has a constant value of 4675 J was the internal heat energy 'ALLIHE'. The value of ALLIHE was highest among all energy variables and is also remaining...

Hello, I ran an Explicit (dynamic, coupled temp-disp) model for friction stir spot welding like process in which the tool penetrates the first layer of the workpiece (two layers, one above the other). The first layer of workpiece is Eulerian whereas the tool is Lagrangian which makes the model...

Hello, Can anyone suggest where can I find how ABAQUS calculates energies (kinetic, internal, dissipation, total, etc.) for a model and what's the definition of the same? I've tried looking in the User's guide and Analysis User's guide but couldn't find anything helpful. I would request you to...

I am trying to delete the elements from a Lagrangian object using Johnson-Cook damage model by specifying zero energy in the damage evolution option. This Lagrangian object is fed against a stationary Eulerian object (completely constrained). In the result, I can observe elements being removed...

Hello, I need to obtain Mises data along an edge based path for the entire period of a step. I have tried using 'path' option and then plotting x-y data but it plots only for a single step frame whereas I am required to get the Mises data for the entire step duration. I also needed some...

Hello, I am struggling in specifying tie constraint between Eulerian material and Lagrangian part as shown in attached image. I have specified translational and angular velocity to the Lagrangian part and want the same be applied to Eulerian material and that's why I am trying to tie the two...

Hello All. I am trying to calculate the 'torque' in a friction stir spot welding simulation by using the formula "Torque= integral of (radius*shear stress)dA". I have divided the pin and shoulder part according to their dimensions. I have seen in the literature that shear stress=flow...

Hello All! I am trying to drill through an Al 6061 alloy layer (1.5mm thick) with a rigid tool (steel alloy). I have used Johnson-Cook plasticity model for both aluminum layer and tool. Also, to remove the elements I have specified JC damage model for aluminum layer with displacement based...

Hello, I am trying to drill through a layer of Aluminum alloy (Al 6061). The model consists of two layers one above the other with Aluminum being on top and steel alloy on the bottom while the tool is made of 4340 steel alloy and is deformable too. The thickness of Aluminum layer is 1.5 mm...

Hello, I needed some opinion about the input parameters. My question is: I have increased the feed rate of a process from 6.5 mm/sec to 120 mm/sec, which is about 18.5 times the original feed rate to complete the analysis in short time to verify if my model works. The process also involves the...

Hello, I'm trying to use ALE adaptive mesh constraint for my model so that the mesh distortion can be avoided. I have tried different settings for mesh constraint, but each time I'm getting the following error "Spatial adaptive mesh constraints can not be specified on nonadaptive node". I am...

Hello, Can someone please help me understand the eulerian outflow boundary condition of 'zero pressure' and 'non-reflecting' (the physical aspect) and how it effects a simulation. (I'm trying to simulate something like friction stir spot welding). I've gone through the ABAQUS documentation, but...

Hello everyone ! I'm currently running a dynamic coupled temp-disp. CEL analysis which has four steps in it with following time period- 0.03, 0.016, 0.03, 0.2 seconds. I'm facing difficulty in completion of the process, as the designated time on cluster computer is not enough for completing the...

Hello Everyone ! I'm doing analysis of a welding process using Coupled Eulerian-Lagrangian approach in ABAQUS/explicit. I have created a model (two layers of workpiece, one eulerian part, and a rigid tool). The tool penetrates the two layers of workpiece (one above the other) and is under...
