Crack growth resistance in plane-stress fracture testing
Engineering Fracture Mechanics, 1972Abstract New developments in crack growth resistance measurement using crack-line-wedge-loaded (CLWL) specimens include improved fixtures, and a double compliance technique for obtaining both load and effective crack length. The latter results in marked improvement in the accuracy of R curves for materials having large plastic zones.

Multifunctional fatigue testing setup for in-plane operating DEAs
Nondestructive Characterization and Monitoring of Advanced Materials, Aerospace, Civil Infrastructure, and Transportation IX, 2020Dielectric Elastomers (DEs) represent a class of soft electro-mechanical transducers, which is promising compared to conventional actuation technologies due to features such as lightweight, high energy efficiency, and low operational noise. Despite several prototypes have been proposed in the recent literature, only very few of them have been ...

In-Plane Experimental Testing of Timber-Concrete Composite Floor Diaphragms
Journal of Structural Engineering, 2010Recent advances in multistory timber building design have led to new structural systems that allow open floor plans with large spans between frames and/or walls. Timber-concrete composite (TCC) flooring can achieve the spans required but has the potential to be flexible under diaphragm actions, which can significantly alter the seismic response of a ...

Testing of In-Plane Shear Properties under Fatigue Loading
Journal of Reinforced Plastics and Composites, 1995A two-dimensional finite element analysis is performed in order to analyze and improve the performance of the three-rail shear test specimen as prescribed by the ASTM Standard Guide for testing of in-plane shear properties of composite laminates [1].

Tests on plates loaded in in-plane compression
Journal of Constructional Steel Research, 1980Abstract The paper discusses the difficulties encountered in supporting the edges of plates when they are tested under in-plane compression, and describes a test rig in which this support is achieved using sets of discrete fingers. The results of tests on structural steel plates are given, in which the magnitudes of residual stresses and initial out ...

In-plane shear testing of graphite-woven fabric composites
Experimental Mechanics, 1994The losipescu shear test method was used to determine the in-plane shear response of AS4 and Celion carbon fiber/epoxy fabric composite materials. Several weave architectures were studied: AS4 uniweave, AS4 and Celion plain weaves, Celion 5-harness and 8-harness satin weaves. Specimens were tested using traditional strain gage techniques and full-field

Cyclic Loading Tests Based on the In-Plane Torsion Test for Sheet Metal
2021In-plane torsion test has attracted a lot of attention recently. As a novel shear test, it can avoid unwanted reaction torque compared with the traditional in-plane shear test. The in-plane torsion test with circular groove specimens can avoid early fracture at the free edges, and thus achieve actual fracture strain under pure shear state because it ...

Use of the Inventory Test in Plane Geometry
The Mathematics Teacher, 1926In the course of the last few years there has been an extensive reorganization of the course of study in mathematics in grades seven, eight, and nine. One phase of this reorganization movement deals with the incorporation of much geometric material.

A Structural Test Facility for In-Plane Biaxial Testing of Advanced Materials
1997A benchmark structural testing facility has been established at the NASA Lewis Research Center (NASA/LeRC). The primary function of this facility is to verify structural analysis methods under prototypical loading conditions. Further, the facility allows the structural integrity of advanced monolithic and composite materials to be evaluated in ...

In-Plane Cyclic Test on Framed Dry-Stack Masonry Panel
Advanced Materials Research, 2010A new masonry system has been developed to improve the seismic behaviour of RC frame with masonry panels. In this system dry-stack masonry panels are built with masonry units capable of sliding in-plane of a panel. These masonry panels have reduced in-plane stiffness but increased frictional energy dissipation capacity compared with the traditional ...
