Stress and deformation analysis of the metal extrusion process
(Elsevier, 1977-03)
A complete stress analysis of a metal-forming process is necessary in order to assess the onset of metal-forming defects such as the initiation of internal or surface cracks or the generation of residual stresses. This ...
Optimal Subassembly Partitioning of Space Frame Structures for In-Process Dimensional Adjustability and Stiffness
(ASME, 2006-05)
A method for optimally synthesizing multicomponent structural assemblies of an aluminum space frame (ASF) vehicle body is presented, which simultaneously considers structural stiffness, manufacturing and assembly costs and ...
Shortest path stochastic control for hybrid electric vehicles
(John Wiley & Sons, Ltd., 2008-09-25)
When a hybrid electric vehicle (HEV) is certified for emissions and fuel economy, its power management system must be charge sustaining over the drive cycle, meaning that the battery state of charge (SOC) must be at least ...
A mesh re-zoning technique for finite element simulations of metal forming processes
(John Wiley & Sons, Ltd, 1986-02)
Based on some fundamental properties of finite element approximations, a mesh re-zoning scheme is proposed for finite element simulations of metal forming problems. It is demonstrated that this technique is indispensable ...
Composite material design of two-dimensional structures using the homogenization design method
(John Wiley & Sons, Ltd., 2001-03-30)
Composite materials of two-dimensional structures are designed using the homogenization design method. The composite material is made of two or three different material phases. Designing the composite material consists of ...
Generalized Serret-Andoyer Transformation and Applications for the Controlled Rigid Body
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
The Serret-Andoyer transformation is a classical method for reducing the free rigid body dynamics, expressed in Eulerian coordinates, to a 2-dimensional Hamiltonian flow. First, we show that this transformation is the ...
Hybrid feedback stabilization of rotational–translational actuator (RTAC) system
(John Wiley & Sons, Ltd., 1998-04-15)
A hybrid feedback control law is proposed for the RTAC system. This hybrid feedback control law is expressed in terms of a continuous feedback part and a part that includes switched parameters determined according to a ...
A family of single-step Houbolt time integration algorithms for structural dynamics
(Elsevier, 1994-09)
A new family of implicit, single-step time integration methods is presented for solving structural dynamics problems. The proposed method is unconditionally stable, second-order accurate and asymptotically annihilating. ...
Understanding and Modeling the Human Driver
(Swets & Zeitlinger - Vehicle System Dynamics, 2003-09)
This paper examines the role of the human driver as the primary control element within the traditional driver-vehicle system. Lateral and longitudinal control tasks such as path-following, obstacle avoidance, and headway ...
