Plastic Hinge and Plastic Zone Seismic Analysis of Frames

2015
The most common approach to perform seismic design of structures is the traditional one based on a linear elastic analysis assumption. On the other hand, nonlinear analysis methods due to their higher complexity and computational cost are mainly applied as a verification tool for the assessment of existing structures.

Inclusion Effect on The Plastic Zone Size in Confined Plasticity

2008
In understanding fatigue properties of metallic alloys, of outmost importance is the precise characterization of the plastic deformation of the material in the vicinity of the crack tip. The plastic behaviour near the tip of stationary growing fatigue crack in engineering materials has been intensively studied using classical plasticity theory based on

Evaluation of the plastic zone in an elastic-plastic dissimilar materials joint

Engineering Fracture Mechanics, 1997
Abstract In a dissimilar materials joint very high stresses develop near the free edge of the interface, even for low mechanical loading or after a homogeneous change of temperature, due to the different mechanical properties and different thermal expansion coefficients of the joined components.

The form of crack tip plastic zones

Engineering Fracture Mechanics, 1984
Abstract The “radius” of the plastic zone at a crack tip is a parameter that has numerous applications in fracture mechanics. However, attention is drawn here to the confusion that is apparent, even in text-books, concerning the calculation of the plastic zone “radius” under plane strain conditions. The aim of this work has been to resolve this point,

Plastic-Zone Analysis of Frames

2018
This chapter describes a refined plastic-zone analysis based on the finite element method. This plastic-zone finite element analysis is applicable to the in-plane analysis of framed structures of arbitrary geometry where the behavior of the members can be described adequately by beam-column theory.

Plastic zones and limit load

Bulletins for applied mathematics, 1995
In this article the foundations of the limit load analysis and its applications in structural design are presented. For the easier comprehension of efficiency of the presented theory, the analysis is limited on a so-called elastic-perfectly plastic material as well as the simple examples.

Track treeing mechanism and plastic zone in solid Part 1: Initial development of plastic zone

Radiation Measurements, 2008
After neutron exposure and chemical etching in advance, latent tracks of recoil nucleon develop into pits on CR39 surface. During electrochemical etching, plastic zone is formed at top of pits. Some pits develop into tree cracks in the initial stage of plastic zone development.

Simplified Theory of Plastic Zones

2017
For a life prediction of structures subjected to variable loads, frequently encountered in mechanical and civil engineering, the cyclically accumulated deformation and the elastic-plastic strain ranges are required. The Simplified Theory of Plastic Zones (STPZ) is a direct method which provides the estimates of these and all other mechanical quantities

Size of the Plastic Zone Produced by Nanoscratching

Tribology Letters, 2017
Nanoscratching of ductile materials creates plastic zones surrounding the scratch groove. We approximate the geometry of these zones by a semicylinder with its axis oriented along the scratch direction. The radius and the length of the cylinder, as well as the length of the dislocations in the network created quantify the plasticity generated.
