For our project, we performed strain sweep (at 1 Hz frequency), frequency sweep (at 1% strain) and magnetic sweep (at 1% strain and 1 Hz frequency) tests on 5 elastomers with varying levels of carbonyl iron particles. The data for all the tests is available in the form of excel files and graphs including the storage modulus, loss modulus and loss tangent. The report was inclusive of these tests and the resulting properties were identified. However, we did not use the data available to us to perform any simulations. Some objections have been made and the clients have asked to include some application to the data. Magnetorheological elastomers are used in vibration isolation applications due to their damping properties for example engine mountings, suspension systems, vibration isolators in LIDAR or other sensors. Due to their properties, any industrial controller can vary the magnetic field and alter the values of the material (i.e. the storage, loss modulus and loss tangent). Hence, for this project, what we need to perform simulations that can explain some application of these materials using the data available to us. A simple 3D model needs to be generated (see example here [login to view URL]) and simulations need to be performed using the data available. One example can be simply using the values are zero magnetic field, and at two other magnetic fields to finding the damping characteristics i.e. how much amplitude has been reduced from the vibrating surface to the base plate. We are open to ideas as the time is short and we totally understand that a huge amount of work can not be done. We just need a sufficient analysis using our data based on a few simulations demonstrating the damping properties of magnetorheological elastomer. The ideal candidate for this job is someone who The ideal candidate for this job is someone who 1. has background in mechanical/materials engineering. 2. Knows part modelling and assembly using SOLIDWORKS or other software. 3. Can perform ABACUS or ANSYS simulations. 4. Has understanding of vibrations and can generate small reports explaining the effectiveness of using elastomers to reduce vibration transfer. 5. Can finish this task in possibly one to two days. (think of this an a book example of vibration reduction using elastomers by ANSYS, COMSOL, ABACUS simulations).

Hi there, My name is Tausif and I have done my PhD in mechanical engineering (system dynamics and smart materials) from Inha University, South Korea. I have been working as a freelancer for more that 7 years in FEA simulations and mathematical modeling. Currently I am working as a postdoctoral researcher in applied acoustics and vibration. MR elastomers is one of the my current projects. However, I did the simulation of MR fluid successfully in my PhD project. And now I am trying to simulate the MR elastomer for my upcoming project. If you are interested then please send me more details about it and we can discuss further. This is highly non linear multiphysics problem and we need to account the effect of magnetic field on the stiffness change of the MR elastomer. In MR fluid that effect can be accounted by modified Bingham model. But here we need to consider the strain energy density function and you can incarporate that into any software. That is the reason I quoted you large amount and it is a trial and error situation. So it will take time. If anyone else give you results more quickly then please just let me know if its successful. Doing only structural analysis or magnetic analysis of MR elastomer is bit simple. But considering the effect of the magnetic field and then taking that into material model is challenging task

SBL's unique BIM services comprise of 3D Laser scanning services which provides user with point clouds and enable 3D BIM modeling for various tasks including building reconstruction and plant layout. We majorly use Bentley Aecosim building designer to support the architectural, structural, MEP and sustainable components of multiple design projects on Rail & Road network, As-built documentation, assets and facility management. Our team is well experienced in creating virtual reality via the realistic 3D models using the LiDar & the photogrammetric data. SBL staff modeled volume of building for Indian and International clients with their required LOD ranging from LOD100 to LOD 400. Our expertises are well conversant with the latest modeling software’s like Bentley Aecosim and Autodesk revit. We also executed a large urban modeling project using ESRI City engine; for the land mass of 2000 hectares using urban planning parameters.
