Analysis of Bending Test Technique for Osteosynthesis Titanium Plate

Abstract Titanium and its alloys often take the role of material for manufacturing the implants for orthopedic use. The purpose of the study is to determine the parameters of bending test of an implantable titanium plate used for osteosynthesis. The method described in the ISO 9585-2011 was analyzed for testing metal plates for fixation of fractured bone fragments. A comparison of the test results for plates on a 4-point bending for two different standards and the results of experiments are reported. The attention is drawn to the possibility of weakening of titanium plates with fixation holes.     Keywords: 4-point bending test, plate for osteosynthesis, titanium implant, mechanical propertie

Allowing for residual stresses in the cross-sections of compressed l-shaped columns during their design

A procedure has been developed for evaluation of the stress-strain state of I-shaped steel columns at all the stages of loading, including the hypercritical region. Design has been performed allowing for the fields of residual stresses, arising in the cross-sections of these columns.Разработана методика оценки напряженно-деформированного состояния стальных двутавровых стержней на всех стадиях нагружения, в том числе и в закритической области. Расчеты проведены с учетом полей остаточных напряжений, возникающих в сечениях этих стержней
