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

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.

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

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 ...

Practical strain extensometry for biaxial cruciform specimens—Part 1
Strain, 1985Of a number of methods for testing materials under biaxial stress conditions, the cruciform specimen with tension/compression loading of the arms allows exploration of the whole in‐plane failure envelope. This paper highlights the problems arising in the measuring, monitoring and control of strains in cruciform specimens subject to static and cyclic ...

On-Line Structural Health Monitoring and Prognosis of a Biaxial Cruciform Specimen
50th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2009The current research of on-line damage state estimation techniques offers adaptive damage state prediction and residual useful life assessment. The real-time damage state information from an on-line state estimation model can be regularly fed to a predictive model to update the residual useful life estimation in the event of a changing situation.

Fatigue damage prediction of cruciform specimen under biaxial loading
Journal of Intelligent Material Systems and Structures, 2012This article investigates an energy-based multiscale damage criterion for a biaxial loading case. The criterion incorporates crystal plasticity at the microscale that produces a damage tensor, representing the local damage state derived from a least squares method.
