Abstract: Yield and fracture criteria for real materials are to a varying degree affected by a state of hydrostatic stress. Some materials, after certain deformation history, exhibit different yield point ...

Abstract: Known yield functions have been constructed in the three-dimensional space of principal stresses. Their convexity in the six-dimensional space of the stress components is only conjectured. ...

Abstract: Plastic materials behave as both solids and fluids. When forced to move in a pipe, they flow as a solid plug with a slipping boundary. Depending on the cross-sectional shape of the pipe, ...

Abstract: In practical applications, plates are often not supported along their boundaries. Properly located interior supports can greatly increase the load-carrying capacity of a plate. The optimal locations ...

Abstract: This paper presents a method and an algorithm for the planning of collision-free paths through obstacles for robots end-effectors or autonomously guided vehicles. Fifth-order nonperiodic B-spline ...

Abstract: This paper investigates theoretical formulations for the radiation and “drag”-dependent hydrodynamic damping mechanisms for vertical bottom-pivoted cylinders under excitation by irregular uni-directional ...

Abstract: Plate vibration is an old subject in mechanics in which the boundary value problems have almost been exhausted. But in practice, very few plates are constrained only along the boundary. Internal ...

Abstract: A differentiation method, which combines the concepts of least squares and splines, has been developed to analyze human motion data. This data smoothing technique is not dependent on a choice ...

Abstract: An approach for the automatic generation and refinement of three-dimensional finite element meshes subdivided by multiply connected, rigid body movable subdomains has been developed. A combination ...
