Since recrystallization temperature measured by the differential scanning calorimetry was 270 C, it can be said that the applicable upper limit is 250 C. However, it is necessary to pay attention for application to a machine element that subjected to high temperature for a long time, such as 200 C × 120 h, since recrystallization is accelerated by keeping high temperature. Since a mechanical energy required for grain growth is increased with decreasing ambient temperature, the nickel foil was applied for the low temperature environment (373K) than the traditional report (473K). Maximum shearing stress that grains grown in 373K was about 1.5 times larger than that in 473K. The calibration equation between the grown grain density, maximum shearing stress, number of cycles and ambient temperature was obtained based on the experimental data. From this equation, the range of measurable shearing stress at various ambient temperatures was calculated and compared with the copper foil. Nickel foil was possible to measure the high shearing stress at low temperatures as compared to the copper foil.","PeriodicalId":282024,"journal":{"name":"Journal of the Japanese Society for Experimental Mechanics","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129681127","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}

It is, therefore, important to know the mechanical characteristics of the PCL. The objective of this study was to evaluate the in vivo characteristics of the three-dimensional (3D) deformation and orientation of the PCL during knee flexion using magnetic resonance imaging (MRI). Ten normal knees were visualized using MRI at full extension (FE), 10°, 20°, 30° and 60° of static knee flexion. The length, strain, elevation and deviation of the PCL were measured using the 3D models of the femur, tibia and PCL reconstructed from the MR images. The PCL length was measured in three portions (Medial: M, Central: C, Lateral: L) to consider its 3D shape. Tendencies of the PCL elongation and strain during knee flexion were different among these 3 portions. The PCL length in M portion was shortest in 10° or 20° and extended in FE and 60°. The PCL length in L portion, on the other hand, extended from FE to 60°. These 3D deformation characteristics were consisted with the changes in the elevation and deviation of the PCL during knee flexion.","PeriodicalId":282024,"journal":{"name":"Journal of the Japanese Society for Experimental Mechanics","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116838268","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}

Therefore, accurate displacement distribution measurement is important to maintain of their structures. Sampling moiré (SM) method is one of the optical full-field displacement measurement method used in field experiments. In the SM method, the in-plane displacement distribution can be accurately determined using a digital camera and repeated patterns. In this study, we developed a dynamic out-of-plane displacement distribution measurement method based on the SM method using a single camera. In the proposed method, the out-of-plane displacement was measured by considering the relationship between the change of grating pitch in captured image and the magnification of used camera lens. Some researchers proposed the out-of-plane displacement distribution measurement methods by using two or multiple cameras. Compared with their methods, our method has advantages including fast, ease-of-use, and inexpensive equipment. The basic principle and an experimental validation of measurement accuracy were presented. As an application, this technique can be potentially extended to measure the out-of-plane direction vibration frequency in full-field.","PeriodicalId":282024,"journal":{"name":"Journal of the Japanese Society for Experimental Mechanics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124924655","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}
