This study evaluated the tensile and flexural strength of tungsten inert gas (TIG) welds in specimens made of commercially pure titanium (CP Ti) compared with laser welds. Sixty cylindrical specimens (2 mm diameter x 55 mm thick) were randomly assigned to 3 groups for each test (n=10): no welding (control), TIG welding (10 V, 36 A, 8 s) and Nd:YAG laser welding (380 V, 8 ms). The specimens were...

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%...

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...

In this paper, the tensile testing method at the intermediate strain rate is established and tensile tests of steel sheets for an auto-body have been performed to evaluate dynamic material properties. A high speed tensile testing machine has been developed for tensile tests at the intermediate strain rate. A simple jig fixture for gripping a specimen has been designed to diminish the load ringi...

In the present study, two types of tests (tensile strength test and polymerization inhibition test) were performed to evaluate the physical and chemical properties of four impression materials [a polysulfide (Permlastic), a polyether (Impregum), a condensation silicone (Xantopren) and a polyvinylsiloxane (Aquasil)] when polymerized in contact with of one conventional (Hemostop) and two experime...

The aim of the work was to evaluate the influence of the temperature of investment healting on the tensile strength and Vickers hardness of CP Ti and Ti-6Al-4V alloy casting. Were obtained for the tensile strength test dumbbell rods that were invested in the Rematitan Plus investment and casting in the Discovery machine cast. Thirty specimens were obtained, fifteen to the CP Titanium and fiftee...
