A programming approach to the solution of problems involving elastic-plastic plates [PDF]

, 1982
Bibliography: leaves 84-88.An extended kinematic minimum principle in classical plasticity is used as the basis for the finite element formulation of the rate problem for elastic-plastic plates. A simple algorithm is used to solve the resulting quadratic

A comparison of plastic collapse and limit loads for single mitred pipe bends under in-plane bending [PDF]

, 2010
This paper presents a comparison of the plastic collapse loads from experimental in-plane bending tests on three 90 degree single un-reinforced mitred pipe bends, with the results from various 3D solid finite element models.

Closed-form dynamic stability criterion for elastic-plastic structures under near-fault ground motions

Frontiers in Built Environment, 2016
A dynamic stability criterion for elastic-plastic structures under near-fault ground motions is derived in closed-form. A negative post-yield stiffness is treated in order to consider the P-delta effect.

Visco-elastic regularization and strain softening [PDF]

, 2006
In this paper it is intended to verify the capacity of regularization of the numerical solution of an elasto-plastic problem with linear strain softening. The finite element method with a displacement approach is used.

Friction Analysis on Scratch Deformation Modes of Visco-Elastic-Plastic Materials [PDF]

, 2012
Understanding of abrasion resistance and associated surfaces deformation mechanisms is of primary importance in materials engineering and design. Instrumented scratch testing has proven to be a useful tool for characterizing the abrasion resistance of ...

Research on Quasi-Elastic–Plastic Optimization of Reinforced Concrete Frame–Shear Wall Structures

Buildings
Precise determination of structural elastic–plastic displacement and component states under rare earthquakes is crucial for structural design. This article proposes a quasi-elastic–plastic optimization method for reinforced concrete structures. First, an

Proppant embedment behavior and elastic–plastic embedding depth modeling of coal reservoirs under multi-stage loading

Meitan xuebao
To investigate the elasto-plastic embedment behavior of proppant during coalbed methane (CBM) production, a mechanical testing system equipped with a high-precision displacement sensor was used to design and conduct proppant-embedment tests under multi ...

Plastic load evaluation for a fixed tube sheet heat exchanger subject to proportional loading [PDF]

, 2012
The plastic load of pressurised components can be calculated based on both the twice elastic slope and tangent methods. Both methods are problematic since they rely on parameters that are localised and therefore have a strong dependency on the gradient ...

Comparisons Between Pull-Out Behaviour of Various Hooked-End Fibres in Normal–High Strength Concretes

International Journal of Concrete Structures and Materials, 2019
In this paper an elastic–plastic response has been developed to predict the pull-out behaviour of various hooked end fibres embedded in normal–high strength concretes.
