Journal ArticleDOI
Uncertainty in mechanics problems-interval-based approach
Rafi L. Muhanna,Robert L. Mullen +1 more
TL;DR: In this article, a nontraditional uncertainty treatment for mechanics problems is presented, where uncertainties are introduced as bounded possible values (intervals) and a very sharp enclosure for the solution set, due to loading, material and geometric uncertainty in solid mechanics problems, is obtained.
Journal ArticleDOI
Analysis of tip deflection and force of a bimetallic cantilever microactuator
TL;DR: In this paper, a model of the electromechanical performance of bimetallic cantilever microactuators by deriving the relationship between the tip deflection and change in temperature using a simple analytical approach is presented.
Journal ArticleDOI
Mixed methods for time integration
TL;DR: Three techniques for enhancing computational efficiency are presented: explicit- Implicit partitions, explicit-explicit partitions with different time steps, and implicit-implicit partitions.
Journal ArticleDOI
Dispersion analysis of finite element semidiscretizations of the two‐dimensional wave equation
Robert L. Mullen,Ted Belytschko +1 more
Journal ArticleDOI
Stability of explicit‐implicit mesh partitions in time integration
Ted Belytschko,Robert L. Mullen +1 more
TL;DR: The stability of time integration for a semidiscretization of structures and continua where the mesh is partitioned into subdomains integrated simultaneously by explicit and implicit methods is considered.
