The study of the tensile behaviour of clay is one of the topics which requires a specific lighting especially when one pays a close attention to the pathology of work built with or on clays subjected to significant tensile forces. Therefore, failure or damage of clay, under specific conditions, can be related to tensile stress limit and not to shear stress limit. It is the case of compacted cla...

Increasing tensile properties and collagen content is a recognized need in articular cartilage tissue engineering. This study tested the hypothesis that multiple applications of chondroitinase ABC (C-ABC), a glycosaminoglycan (GAG) degrading enzyme, could increase construct tensile properties in a scaffold-less approach for articular cartilage tissue engineering. Developing constructs were trea...

The present study deals with the experimental analysis and mechanical modeling of tensile behavior of brain soft tissue. A transversely isotropic hyperelastic model recently proposed by Meaney (2003) is adopted and mathematically studied under uniaxial loading conditions. Material parameter estimates are obtained through tensile tests on porcine brain materials accounting for regional and direc...

The goal of the study, is to specify mechanical properties of epoxy and acrylic-based adhesives commonly used for bonding of metal connections. For this reason, the bulk specimens, manufactured from Devcon A and Akfix-E300 as epoxy material, Erde GTR and Erde GTS as acrylic based adhesive material, were cast in accordance with the test standards. The mechanical properties of the specimens obtai...

Experimental study on the influence of fibre content on crack behaviour and propagation in synthetic-fibre reinforced beams has been reported in this paper. The tensile behaviour of metallic fibre concrete is evaluated in terms of residual flexural tensile strength values determined from the load-crack mouth opening displacement curve or load-deflection curve obtained by applying a centre-point...

Unreinforced masonry is that in which the tensile strength of the masonry is taken into consideration in design. Allowable out-of-plane tensile stress values are a function of the mortar type, such as Portland cement/lime mortar vs. masonry cement mortar or type M or S mortar vs. type N mortar. The allowable tensile stress is also a function of the masonry construction, such as tension parallel...

The ma~tensitic transfol-niation (MT) under tensile dcfol.m:ltion at 77K i n a series of FeNi-Mn alloys was studied. The anlotult of ~na~tensite fos~ned d ~ ~ r i ~ l g the tensile test depends on the applied stress and on the Mn content which determines the mnrtensitic point and the MT start stress. Elongation of the tensile tested samples has a maximum value in the alloys co~ltainilig the 50%...

In this paper, the inelastic damage process in Engineered Cementitious Composites (ECC) in the high stress concentration zone adjacent to the head of an embedded anchor under tensile load was examined experimentally and numerically. An FEM model together with a tensile strain-hardening material model of ECC was developed to simulate the damage process leading to final failure. Experimental obse...

Poly (lactic acid) (PLA) is biodegradable, melt processable and environmentally benign aliphatic polyester produced from the fermentation of natural renewable resources like corn, sugar and vegetable. The comparative analysis of the effect of time of heatsetting and wet processing from this research showed that PLA exhibited good textile properties for versatile end applications. This research ...

We explore BiFeO3 under tensile strain using first-principles calculations. We find that the actual structures are more complex than what had been previously thought, and that there is a strong shear deformation type structural instability which modifies the properties. Specifically, we find that normal tensile strain leads to structural instabilities with a large induced shear deformation in (...
