Dynamic Response Analysis of Elastic-plastic Structures with Component Mode Synthesis [PDF]
MATEC Web of Conferences, 2017 This paper evaluates the validity of component mode synthesis (CMS) technique for dynamic response of elastic-plastic structures. A method incorporating elastic-plastic material behaviour and the fixed interface mode synthesis technology is presented. To

Elastic-plastic response of mild steel beams to impulse loads [PDF]
, 1977 The elastic-plastic response of 1018 steel beams was examined experimentally and analytically. Simply supported beams were loaded with half-sine distributed, short-duration magnetic pressure pulses and the response monitored with a streak camera and strain gages.

Characterising plastic collapse of pipe bend structures [PDF]
, 2006 Two recently proposed design by analysis criteria of plastic collapse based on plastic work concepts, the plastic work (PW) criterion and the plastic work curvature (PWC) criterion, are applied to a strain hardening pipe bend arrangement subject to ...

A fully implicit, lower bound, multi-axial solution strategy for direct ratchet boundary evaluation : theoretical development [PDF]
, 2013 Ensuring sufficient safety against ratchet is a fundamental requirement in pressure vessel design. Determining the ratchet boundary can prove difficult and computationally expensive when using a full elastic-plastic finite element analysis and a number ...

Reaching the Yield Point of a Glass During X-Ray Irradiation
Physical Review X, 2023 A solid loaded beyond the yield stress loses its elastic properties and becomes plastic. From a microscopic point of view, this limit corresponds to the condition where plastic regions become so densely packed that they give rise to system-spanning ...

Gross plastic deformation of axisymmetric pressure vessel heads [PDF]
, 2006 The gross plastic deformation and associated plastic loads of four axisymmetric torispherical pressure vessels are determined by two criteria of plastic collapse: the ASME twice elastic slope (TES) criterion and the recently proposed plastic work ...

Design by analysis of ductile failure and buckling in torispherical pressure vessel heads [PDF]
, 2007 Thin shell torispherical pressure vessel heads are known to exhibit complex elastic-plastic deformation and buckling behaviour under static pressure. In pressure vessel Design by Analysis, the designer is required to assess both of these behaviour modes ...

Frontiers in Built Environment, 2017 A set of multiple impulses is introduced as a substitute of many-cycle harmonic waves which represent the long-duration earthquake ground motion. A closed-form expression is derived of the elastic–plastic response of a single-degree-of-freedom structure ...
