Constitutive model for plasticity in an amorphous polycarbonate [PDF]
, 2007 A constitutive model for describing the mechanical response of an amorphous glassy polycarbonate is proposed. The model is based on an isotropic elastic phase surrounded by an SO(3) continuum of plastic phases onto which the elastic phase can collapse ...

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 ...

Descriptions of reversed yielding in bending [PDF]
, 2007 Existence of Bauschinger effect in bending-unbending of copper beams has been shown from experiment. In modelling of the Bauschinger effect, it is shown that a significant second plastic penetration can occur with the release of the moment required for ...

Elastic-Plastic Response Charts for Nuclear Overpressures [PDF]
, 1984 Abstract : The single-degree-of-freedom equation of motion for an elastic- plastic system with forcing functions that are representative of nuclear weapon simulations is nondimensionalized and solved. Numerical solutions are calculated by the Newmark Beta method, and response charts incorporating nondimensionalized structural and loading parameters for

Nanoscale Molecular Dynamics Simulaton of Shock Compression of Silicon [PDF]
, 2005 We report results of molecular dynamics simulation of shock wave propagation in silicon in [100], [110], and [111] directions obtained using a classical environment-dependent interatomic potential (EDIP).

Dynamic Response Analysis of Elastic-plastic Structures with Component Mode Synthesis
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

Frontiers in Built Environment, 2016 The double impulse is introduced as a substitute of the fling-step near-fault ground motion. A closed-form solution of the elastic-plastic response of a structure on compliant (flexible) ground by the ‘critical double impulse’ is derived for the first ...
