Tensile Test For Arboform Samples

High-speed tensile test instrument.

A novel high-speed tensile test instrument is described, capable of measuring the mechanical response of elastomers at strain rates ranging from 10 to 1600 s(-1) for strains through failure. The device employs a drop weight that engages levers to stretch a sample on a horizontal track. To improve dynamic equilibrium, a common problem in high speed testing, equal and opposite loading was applied...

A Conditional Test for Exponentiality Against Weibull DFR Alternatives Based on Censored‎ ‎Samples

‎A conditional test based on quadratic form using type-2 censored sample for testing exponentiality against Weibull alternative is proposed‎. ‎The simulated percentage points and powers are given‎. ‎The proposed test performs well for identifying Weibull DFR alternative even for small sample‎. ‎An example is also given.

A Test for Weibull IFR/DFR Alternatives Based on Type-2 with Replacement Censored Samples

This article presents a test based on quadratic form using Type-2 with replacement-censored sample for testing exponentiality against weibull IFR/DFR alternative. The percentile points and powers are simulated. The proposed test is compared with that of Bain and Engelhardt (1986) test. An example based on Type-2 censoring is also discussed.

Identification of Orthotropic Plate Stiffness Using Open Hole Tensile Test

Identification of mechanical parameters is still a challenge on real structures. With the improvement of optical full field measurement techniques, it becomes easier, but in spite of many publications showing the feasibility of such methods, experimental results are still scarce. We present here a first step towards a global approach of mechanical identification for composite materials. The cho...
