Postdoctoral Research Associate - Computational Solid Mechanics for Digital Cert/Qual

About the role

We are seeking a Postdoctoral Research Associate who will use multiscale modeling and simulation to develop probabilistic life-lining frameworks for high-temperature alloys and extreme environment structural materials. A strong background in mechanical behavior of materials is required. Demonstrated experience in the implementation of nonlinear constitutive models in commercial (e.g. Abaqus, ANSYS, etc.) and/or open-source finite element (FE) codes (e.g., MOOSE, DAMASK, etc.) is required. Experience with microstructural modeling (e.g. crystal plasticity) applied to fatigue and ductile fracture is preferred. You will be expected to collaborate with research staff and industry partners to support certification and qualification efforts for components produced by various advanced manufacturing processes.

Responsibilities

• Participate in the development and implementation of nonlinear constitutive models into FE codes.
• Participate in the development and implementation of crystal plasticity constitutive models into FE codes for additively manufactured alloys.
• Participate in the development of probabilistic life-lining approaches for additively manufactured materials using multiscale modeling.
• Present and report research results at workshops and conferences and publish key findings in peer-reviewed journals in a timely manner.
• Collaborate within a multi-disciplinary research environment consisting of computational scientists, experimentalists, and engineers conducting basic and applied research in support of the Laboratory’s missions.
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Qualifications

• Ph.D. in materials science and engineering, mechanical engineering, or a field relevant to the job duties within the past 5 years.
• A strong background in mechanical behavior of materials is required.
• Experience in the development and implementation of constitutive models within commercial and/or open-source finite element software is required.
• Demonstrated expertise in multi-physics FE simulations is preferred.
• Demonstrated expertise in using machine learning and optimization frameworks in conjunction with FE simulations to assist with component and/or process design is preferred.
• Excellent written and oral communication skills.
• Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
• Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.
