Support Vector Machines for Estimating Decision Boundaries with Numerical Simulations

Walsh, Timothy W.; Aquino, Wilkins A.; Kurzawski, Andrew K.; McCormick, Cameron M.; Sanders, Clay M.; Smith, Chandler B.; Treweek, Benjamin T.

Many engineering design problems can be formulated as decisions between two possible options. This is the case, for example, when a quantity of interest must be maintained below or above some threshold. The threshold thereby determines which input parameters lead to which option, and creates a boundary between the two options known as the decision boundary. This report details a machine learning approach for estimating decision boundaries, based on support vector machines (SVMs), that is amenable to large scale computational simulations. Because it is computationally expensive to evaluate each training sample, the approach iteratively estimates the decision boundary in a manner that requires relatively few training samples to glean useful estimates. The approach is then demonstrated on three example problems from structural mechanics and heat transport.

Sierra/SolidMechanics 5.8 User's Manual

Bergel, Guy L.; Beckwith, Frank B.; de Frias, Gabriel J.; Manktelow, Kevin M.; Merewether, Mark T.; Miller, Scott T.; Parmar, Krishen J.; Shelton, Timothy S.; Thomas, Jesse T.; Trageser, Jeremy T.; Treweek, Benjamin T.; Veilleux, Michael V.; Wagman, Ellen B.

Sierra/SolidMechanics (Sierra/SM) is a Lagrangian, three-dimensional code for finite element analysis of solids and structures. It provides capabilities for explicit dynamic, implicit quasistatic and dynamic analyses. The explicit dynamics capabilities allow for the efficient and robust solution of models with extensive contact subjected to large, suddenly applied loads. For implicit problems, Sierra/SM uses a multi-level iterative solver, which enables it to effectively solve problems with large deformations, nonlinear material behavior, and contact. Sierra/SM has a versatile library of continuum and structural elements, and a large library of material models. The code is written for parallel computing environments enabling scalable solutions of extremely large problems for both implicit and explicit analyses. It is built on the SIERRA Framework, which facilitates coupling with other SIERRA mechanics codes. This document describes the functionality and input syntax for Sierra/SM.

Sierra/SolidMechanics 5.6 User's Manual

Bergel, Guy L.; Beckwith, Frank B.; de Frias, Gabriel J.; Manktelow, Kevin M.; Merewether, Mark T.; Miller, Scott T.; Parmar, Krishen J.; Shelton, Timothy S.; Thomas, Jesse T.; Trageser, Jeremy T.; Treweek, Benjamin T.; Veilleux, Michael V.; Wagman, Ellen B.

Sierra/SolidMechanics (Sierra/SM) is a three-dimensional solid mechanics code with a versatile element library, nonlinear material models, large deformation capabilities, and contact. It is built on the SIERRA Framework. SIERRA provides a data management framework in a parallel computing environment that allows the addition of capabilities in a modular fashion. Contact capabilities are parallel and scalable. This document provides information about the functionality in Sierra/SM and the command structure required to access this functionality in a user input file. This document is divided into chapters based primarily on functionality. For example, the command structure related to the use of various element types is grouped in one chapter; descriptions of material models are grouped in another chapter. Sierra/SM provides both explicit transient dynamics and implicit quasistatics and dynamics capabilities. Both the explicit and implicit modules are highly scalable in a parallel computing environment. In the past, the explicit and implicit capabilities were provided by two separate codes, known as Presto and Adagio, respectively. These capabilities have been consolidated into a single code. The executable is named Adagio, but it provides the full suite of solid mechanics capabilities, for both implicit and explicit. The Presto executable has been disabled as a consequence of this consolidation.

These alternate versions are enhanced to provide capabilities that are regulated under the U.S. Department of State's International Traffic in Arms Regulations (ITAR) export control rules. The ITAR regulated codes are only distributed to entities that comply with the ITAR export control requirements. The ITAR enhancements to Sierra/SM include material models with an energy-dependent pressure response (appropriate for very large deformations and strain rates) and capabilities for blast modeling. This document is an addendum only; the standard Sierra/SolidMechanics 4.56 User's Guide should be referenced for most general descriptions of code capability and use.

Sierra/SolidMechanics 4.56 Capabilities In Development

Merewether, Mark T.; Plews, Julia A.; de Frias, Gabriel J.; Mosby, Matthew D.; Porter, V.L.; Shelton, Timothy S.; Thomas, Jesse D.; Tupek, Michael R.; Veilleux, Michael V.; Manktelow, Kevin M.; Beckwith, Frank B.; Belcourt, Kenneth N.; Miller, Scott T.; Treweek, Benjamin T.; Wagman, Ellen B.; Koester, Jacob K.

This user's guide documents capabilities in Sierra/SolidMechanics which remain "in-development" and thus are not tested and hardened to the standards of capabilities listed in Sierra/SM 4.56 User's Guide. Capabilities documented herein are available in Sierra/SM for experimental use only until their official release. These capabilities include, but are not limited to, novel discretization approaches such as peridynamics and the reproducing kernel particle method (RKPM), numerical fracture and failure modeling aids such as the extended finite element method (XFEM) and J-integral, explicit time step control techniques, dynamic mesh rebalancing, as well as a variety of new material models and finite element formulations.

Beckwith, Frank B.; Belcourt, Kenneth N.; de Frias, Gabriel J.; Koester, Jacob K.; Manktelow, Kevin M.; Merewether, Mark T.; Miller, Scott T.; Mosby, Matthew D.; Plews, Julia A.; Porter, V.L.; Shelton, Timothy S.; Thomas, Jesse T.; Treweek, Benjamin T.; Tupek, Michael R.; Veilleux, Michael V.; Wagman, Ellen B.

Presented in this document are the theoretical aspects of capabilities contained in the Sierra/SM code. This manuscript serves as an ideal starting point for understanding the theoretical foundations of the code. For a comprehensive study of these capabilities, the reader is encouraged to explore the many references to scientific articles and textbooks contained in this manual. It is important to point out that some capabilities are still in development and may not be presented in this document. Further updates to this manuscript will be made as these capabilities come closer to production level.
