Tensile tests were done at INCAS Bucharest and the presented results are values obtained on 5 bone samples. There were analyzed the following characteristics: Young modulus, stress peak at break, elongation at break and energy at break. Greater deformation rates, when testing at traction, rises the tensile stress limit and diminishes the strain at which the polymer samples break. PA6 and PP exhibit different behaviors. PA6 yields at very low deformation rate, having a high strain at break (0.9) when it is tested at 10 mm/min, but reducing this characteristic for higher deformation rates. PP has similar curves for the tested deformation rates, but with lower tensile stress limit when tested under lower deformation rate. These data are useful when designing polymeric components bearing different strain rates.","PeriodicalId":125331,"journal":{"name":"Mechanical Testing and Diagnosis","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116738457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained in the industrial parter floor show the structure's ability to withstand standard wind and snow loads, but also after a possible earthquake. After the static analysis, values close to the norm-accepted limit were recorded. The advantage of metallic constructions in the field of industrial halls is obvious: weight reduction compared to reinforced concrete constructions; increased safety due to the homogeneity of steels; reduced execution time, etc. In combined cases for determining the ultimate fundamental load the maximum combined bending stresses and axial stresses do not exceed the 150 MPa admissible stress; the largest combined stresses are recorded in the bundles and not the length of the bars, with regard to the welding connection of the bar elements (roof and upper longitudinal bracings). The maximum total displacements of the rolling bridge are in accordance with the applicable regulations (arrow / bar length <1/600). Relative displacements greater than 1/600 are recorded in bars without technological importance. The track of the bridge is relatively less influenced by the action of the external loads of the hall, it is supported by its own pillars.
