An apparatus is described which is capable of measuring the load-displacement characteristics as well as determining the loci of centers of rotation of articulating joints. The apparatus employs a floating head which permits the axis of rotation to coincide with the position of minimum joint resistance, thus eliminating non-physiological rotations at the joint. The coupled loads are also measured, thus providing an accurate description of the joint structural characteristics. Data taken from a freshly amputated human ankle joint is presented.

Using fiber optics as a tool for different kinds of geotechnical monitoring can be highly attractive and cost-effective when compared to conventional instruments, such as piezometers and inclinometers, among others. A single fiber optic cable may cover a larger monitoring area compared to conventional instrumentation and allows for monitoring more than one physical quantity with the same fiber optic cable. The literature provides several different examples of distributed fiber optic systems usage.

Subretinal injection of gene products is the only treatment option for inherited retinal diseases. However, this procedure induces localized high multiaxial deformations, potentially causing irreversible tissue damage due to retinal overstretching and tearing. Comprehensive characterization of retinal mechanical behavior is essential for performing safe injections.

In lightweight design, the usage of different optimised materials is widespread. The interfaces between two different materials are prone to damage and, therefore, the Structural Health Monitoring (SHM) of these areas is of interest. A new method for the damage evaluation of joints is developed and validated.

Article Synopsis
- The study investigates the bearing characteristics of rock-socketed single piles in Fujian Province using material tests and model tests that simulate weathered granite properties.
- Ten groups of sample materials were created, and Specimen 1 was found to best represent the desired mechanical properties after thorough testing, including triaxial testing.
- Results from applying horizontal and vertical loads showed that the pile behaves as a flexible structure, providing crucial insights for designing single pile foundations in weathered granite areas, particularly for offshore wind energy projects.
Relationship between the microstructural energy release rate of cortical bone and age under compression condition.

Most studies evaluated the energy release rate of cortical bone macrostructure under Mode I, Mode II, and mixed Mode I-II loading conditions. However, testing the macrostructural energy release rate requires an initial crack and recording the applied load and the corresponding crack length in real-time, which may introduce measurement errors and differences with the actual fracture scenarios. To further understand how the energy release rate contributed to the cortical bone fracture characteristics, this study predicted the microstructural energy release rate of cortical bone and then investigated its age-related varitions.
