The Automated Computational Mechanics Laboratory (ACML) at The Ohio State University has an immediate opening for a one-year postdoctoral research associate position. The project is aimed at the application of the finite element method for simulating and optimizing the multiphysics laser ablation process in aircrafts. The optimization process involves characterizing the optimal laser parameters (e.g., peak power, fluence, intensity, etc.) to maximize the coating removal efficiency while minimizing damage to the substrate material.
Applications are invited for one PhD position (4 years) in the area of atomistic-based modelling of polymer composite degradation at Delft University of Technology in the Netherlands.
The successful applicant will work with Dr. Angelo Simone (Computational Mechanics of Materials Group) and Prof. Barend Thijsse (Virtual Materials and Mechanics Group) on a project funded by the Technology Foundation STW through the High Tech Materials program. The position is to commence in spring/summer 2015 or as soon as possible thereafter.
Veryst Engineering has an opening for a Multiphysics Simulation Engineer to work on problems involving fluid flow, structural mechanics, heat transfer and/or acoustics. Responsibilities include engineering analysis and design. Ph.D. or Masters Degree in mechanical engineering, biomedical engineering, aeronautical engineering, or physics with some industrial experience preferred. Strong academic record and references necessary. Experience with COMSOL Multiphysics, ANSYS, and/or Abaqus is desirable.
The Multifunctional Materials Branch of the Materials Science & Technology Division at the US Naval Research Laboratory in Washington DC has an interest in postdoctoral associate candidates for several areas in computational mechanics and multiphysics.

Abaqus 6.13 - Live Webinar! July 23, 9am EDT and 12 pm EDT. The latest release, Abaqus 6.13 delivers a number of powerful, customer-requested enhancements for modeling, meshing, visualization, contact, mechanics, and performance. These improvements enable customers to reduce development time and costs, while increasing the efficiency of the product development process through highly accurate simulations of real-world product and material behavior.
The approach to modeling soil is validated by comparing predicted traction of a trolling rigid wheel to measured traction test date available in the literature. Comparison of the measured and predicted traction force shows that this approach is reasonable for predictin traction in soil.
This paper presents an automated approach to extract strains of aircraft structural models from widely used CAD and FE environments. The developed approach has been implemented as an integrated tool in widely used CATIA V5 and Abaqus environment. The integrated tool is a quick inexpensive and effecive technique for predicting structural strains.
In this paper, the different "built in" material models based on the isotropic, kinematic and combined istropic-kinematic hardening theories available in Abaqus/Standard are evaluated for carbon steels. The results presented in this study are expected to provide important insight to practicing engineers dealing with inelastic material characteristics.
This study demonstrates a simulation of an integrated multilink suspension system model in
Abaqus. The model is assessed in Abaqus to determine the suspension strength and fatigue life of each individual link. This topological design optimization is executed for this multilink suspension model using ATOM to determine the critical load path, alternative concept designs, and locations for mass reduction in order to meet the performance requirements.
This paper describes the parameter-based geometrical optimization of a thrust collar bearing. The thrust bearing, for example, has to carry the whole axial force of the rotor with only minimal deformation of the collar surface over the turbocharger’s complete operating range.
This paper discusses a method to address this challenge by the creation of a moving
tie constraint via the MPC user routine. This approach allows the change in weight; change in inertia and effects of fluid momentum to be correctly and conveniently captured using dynamic modelling.
The objective of this paper is to use Abaqus/Standard to compute elastic-plastic J-integral results along the crack front. These results are then used to calculate the plastic collapse crack reference stress, especially for cases when the reference stress solution is not available for a structural component.
The paper covers foundation performance issues and applications for pile-founded, gravity base, and deep water structures. Many of the significant applications were complemented by extensive experimental test programs to confirm or validate the analyses.
The principal objective was to ensure reliable design of the large size bearing test rig. The main challenge here concerned the simulation method for representing the complex mechanical construction of the machine with sufficient precision in an FE model.
This paper examines the performance characteristics of Abaqus 6.11 release for the latest GPU computing technology. The results are provided for finite element models with material, geometric and boundary nonlinearities relevant to current practice in the oil and gas industry, on workstation configurations, including a network of workstations.
This paper presents a detailed investigation of the interactions and interplay among these parameters as evidenced by the nonlinear response of the panel. The study focuses on the nonlinear response of the skin panel under combined thermal and structural loading.
In this paper, a failure criterion and damage properties are investigated to model delaminations in composite parts. Different modeling techniques are explored to evaluate their ability to replicate experimental results.
The ability of the design tool to predict part quality based on manufacturing process parameters is dependent upon the mechanical behavior of the fabric reinforcements, which includes the in-plane shearing and tensile behaviors, bending stiffness and friction between contacting surfaces during the manufacturing process.
This paper discusses the use of such advanced technique to solve the stent design problems. The paper would cover the essence of Finite Element Analysis, FE Model Parameterization and Optimization. Finite element modeling (FEM) and analysis with SIMULIA is used to estimate stress distribution in the stent.
