‘Living’ or plastic hinges

1999
‘Living’, plastic or molded-in hinges are integrated and flexible connections between two pieces of a molded polymer part. Due to the hinges, a motion of the two pieces relative to each other is possible. The main advantage of plastic hinges is the simultaneous production of the polymer part as well as the hinge. Because of this single production step,

A plastic hinge analog

Building Science, 1970
Abstract Analog techniques are frequently useful to the engineer when solving design problems. A simple d.c. electrical analog is described which enables the design engineer to locate and quantify the formation of plastic hinges in steel frame construction.

The Plastic Hinge

2015
The plastic hinge is a key concept of the theory of frames that differentiates this theory from the remaining models for structural analysis. This chapter is exclusively dedicated to define this concept and describe the different models of plastic hinges.

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.

Second-Order Plastic Hinge Analysis

1995
During the past 20 years, numerous analytical models have been developed for second-order inelastic analysis of steel frames. In general, these models may be categorized into two main types: (1) plastic zone and (2) plastic hinge. The plastic-zone model follows explicitly the gradual spread of yielding throughout the volume of the structure ...

Lumped Deformations: a Plastic Hinge Approach

2009
The design requirements of advanced mechanical and structural systems exploit the ease of use of the powerful computational resources available today to create virtual prototyping environments. These advanced simulation facilities play a fundamental role in the study of systems that undergo large rigid body motion while their components experience ...

Rigid Multibody Systems: The Plastic Hinge Approach

2001
Multibody systems are generally complex arrangements of structural and mechanical subsystems with different design purposes and mechanical behavior. Depending on the type of applications, operating speeds, external or internal loading of the components, the multibody system may experience small or large deformations that lead to a change of the system ...

Size effects in plastic hinges of reinforced concrete members [PDF]

, 2002
Reasons for size dependence of rotation capacity of plastic hinges are discussed. The increase of ductility with decreasing member size is interpreted from the viewpoint of fracture mechanics of concrete. The results of the introductory test series on simply supported slender beams loaded in three-point bending are discussed.
