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 ...

Instability behaviour of Changi sand in plane-strain tests
2009Flowslide is a common type of failure of granular soil slopes. Although many flowslides can be explained using static liquefaction or instability behaviour of sand under undrained conditions, some of the failures might have occurred under essentially drained conditions, e.g. the Wachusett Dam case in 1907. Recent laboratory studies on Changi sand under

Determining cyclic flow curves using the in-plane torsion test
CIRP Annals, 2015Abstract A new method of determining cyclic stress–strain curves for characterizing kinematic hardening of sheet materials is introduced utilizing the in-plane torsion test and optical strain measurement. The test enables the simultaneous recording of multiple cyclic stress–strain curves with different amplitudes of plastic strain at load reversal in

Design and Testing of In-Plane MEMS High-g Accelerometer
Applied Mechanics and Materials, 2012μAiming at the demand of missile fuse and other weapons systems, a high-g piezoresistive accelerometer with two terminal fixed beam-mass structure which can measure in-plane acceleration was designed. The design and simulation were also performed using Matlab and ANSYS.

In-plane fracture toughness testing of paper using thermography
Tappi Journal, 1997The temperature distribution of a paper sheet during fracture toughness testing was successively observed as a series of color images by means of an infrared thermography system with close-up lens. No stress concentration accompanied by plastic deformation occurs within the deep double-edge notched tension specimen except around notch tips. A uniformly
