Optimal design of biaxial tensile cruciform specimens
Journal of the Mechanics and Physics of Solids, 1993Abstract F or experimental investigations concerning the mechanical behaviour under biaxial stress states of rolled sheet metals, mostly cruciform flat specimens are used. By means of empirical methods, different specimen geometries have been proposed in the literature. In order to evaluate the suitability of a specimen design, a mathematically well

On the identification of an effective cross section for a cruciform specimen
Strain, 2017AbstractBiaxial tensile testing of sheet metals is becoming increasingly popular for sheet metal forming. Determining equivalent stresses in biaxial tensile specimens is more complicated than in conventional uniaxial tensile specimens. In the present study, we compare four different approaches to calculate effective stresses during biaxial tensile ...

Design of a biaxial extensometer for measuring strains in cruciform specimens
Experimental Mechanics, 1992A biaxial extensometer for measuring strains in flat cruciform specimens is presented. This extensometer allows for the use of two displacement or strain transducers to control and measure strains along mutually orthogonal directions in the plane of the specimen.

Development of an apparatus for biaxial testing using cruciform specimens
Experimental Mechanics, 1992A testing apparatus has been developed to study the behavior of sheet metals and composite materials under monotonic and cyclic biaxial loading conditions. This test facility employs cruciform specimens that are loaded in their plane. Problems encountered while developing the test system are discussed.

Numerical Study of Cruciform Specimens for Biaxial Tensile Tests
Volume 14: Emerging Technologies; Materials: Genetics to Structures; Safety Engineering and Risk Analysis, 2016This paper presents a numerical study of different geometries of cruciform specimens for biaxial tensile tests. The aim of these specimens is to be used on fixtures for biaxial tests mounted in universal testing machines. For the study, a model of isotropic material for steel sheet metal specimens was considered. Thus, only the mechanical properties of

Overview of NESC-IV Cruciform Specimen Test Results
Service Experience and Failure Assessment Applications, 2002NESC-IV is an experimental/analytical program to develop validated analysis methods for transferring fracture toughness data generated on standard test specimens to shallow flaws in reactor pressure vessel welds subject to biaxial loading in the lower-transition temperature region. It is the fourth major project of the Network for Evaluating Structural

Biaxial Testing Using Cruciform Specimens
1986Uniaxial test data for use in design of components and structures operating at high temperatures has been the sole means of predicting deformation and rupture. The majority of components and structures operating at high temperatures are subjected to biaxial or triaxial stress.

A CRUCIFORM SPECIMEN FOR THE EVALUATION OF BIAXIAL PROPERTIES OF ADVANCED COMPOSITES
Transactions of the Canadian Society for Mechanical Engineering, 1995A cruciform specimen to be used for the evaluation of the biaxial elastic and strength properties of fiber-reinforced laminae is presented. The specimen features a hybrid graphite/epoxy-glass/epoxy lay-up in its arms and a stepwise transition from the arms to the gauge zone.

Stress State Evaluation in Biaxially Loaded Cruciform Specimens
Applied Mechanics and Materials, 2015Testing cruciform specimens under static biaxial loading conditions is the method with the best results used to determine the mechanical behavior of materials. A static stress with nonlinear material analysis was applied for only one-eighth of the specimen geometry, due to symmetry conditions, to evaluate stress state from different cruciform specimens

Comparison of Different Techniques for Strain Monitoring of a Biaxially Loaded Cruciform Specimen
Strain, 2011Abstract: This study focuses on the evaluation of several strain measuring techniques for the instrumentation of an in‐plane biaxial test bench. Strain gages, electronic speckle pattern interferometry (ESPI) and digital image correlation (DIC) were used combined or separately to measure the strains in the central gauge area of a biaxially loaded ...
