job

The Multi-Physics Modeling and Simulation Department at Sandia National Laboratories, California, is seeking a technical staff member to develop finite element-based simulation codes for linear and nonlinear solid mechanics and/or to perform solid mechanics and structural dynamics modeling and simulation. Typical departmental programs include: detailed analyses of weapon systems; design guidance of weapon components through analysis; development of forging and welding modeling capabilities; pressure vessel analysis including aging and failure; penetration modeling; ground shock and hydrodynamics modeling and simulations; failure model development and implementation (metals and composites); thermal and dynamic analysis of artillery projectiles; and electromagnetics and EM wave propagation analysis.

Postdoc position in the modeling and simulation of fracture available at Sandia National Labs, Livermore, CA

job

The Mechanics of Materials Department performs fundamental experimental and analytical studies to understand the mechanical behavior of materials. Our experimental work covers the entire discovery-characterization-validation spectrum. Motivated by theory and observations, we develop models and the necessary numerical methods to simulate both deformation and failure under various mechanical and environmental loading conditions. The fidelity of our models and simulations varies from atomic to
continuum scales and is driven by both fundamental studies in material behavior and specific Sandia applications.

We are seeking a post-doctoral candidate with experience and interest in developing numerical methods and models for fracture to assist with a variety of material failure modeling and simulation activities. Knowledge of fracture mechanics and experience in numerical methods and code development are required. Also desired is experience with computational fracture methods, such as adaptive insertion, strain localization, and partition of unity methods for incorporating cohesive zone approaches to modeling fracture in a finite element framework. The position offers a unique opportunity to work closely with our team of fracture and
constitutive model developers, material scientists, experimentalists and analysts to investigate and model material failure in a variety of materials and systems from atomistic to continuum length scales.

The Mechanics of Materials Department performs experimental and analytical studies to understand the mechanical behavior of materials. Our experimental work covers the entire discoverycharacterization-
validation spectrum. Motivated by observations, we develop models to simulate material responses under various loading and environmental conditions. The fidelity of our models and simulations vary from atomic to continuum scales corresponding to the requirement of Sandia applications. Accuracy of the models for specific applications is validated by experimental data. Numerical codes are developed to allow implementation of the
material models for high performance computing simulations.

The highly motivated scientist or engineer with expertise in experimental mechanics will work as a part of a diverse team in our state-of-the-art laboratories. The applicant is expected to develop and apply experimental research methods in one or more of several research areas, including: material model development, failure
model development, rate-dependent material effects and advanced experimental methods/diagnostic technique development.

An applied mechanics engineer with a background in computational constitutive modeling development is sought to participate in our general continuum and multiscale model development effort. The applicant is also expected to implement models into Sandia computer codes for high performance computing simulations. In addition, the candidate will collaborate with structural analysts to apply these advanced models to Sandia applications.

conference

Introduction:

This is the Fifteenth Conference in Mechanical Engineering series that started in 1992. The conference is concerned with the latest in theoretical, mathematical and scientific developments in Mechanical Engineering as well as application of established techniques to new domains. Following tradition of conference, ISME 2007 will provide an international technical forum for experts and researches from both the academia and industry to meet and exchange new ideas and present their findings of ongoing research in various Mechanical engineering disciplines.
