Fatigue Testing of Artificial Joint Materials with Working Waves

Application News - Fatigue Testing of Artificial Joint Materials with Working Waves PDF

In this article, a case is presented in which the force applied to an ankle joint during walking was actually applied to a specimen. First, the TM5135, a compact telemetry system manufactured by Toyota Technical Development Corporation shown in Fig. 1, was used to measure strain data during walking and to generate force waveforms. Next, the generated force waveforms were loaded into a fatigue testing machine, and the force was applied to a square polyethylene material (23.5×23.5×12mm) used as an artificial ankle joint material.

Medical equipment manufacturers and research organizations around the world are conducting research and development into medical equipment based on mechanical properties evaluation and finite-element analysis. Shimadzu Corporation is applying the technical expertise cultivated through physical testing, quality control, and full-scale testing in materials development to the fields of leading-edge medicine and biomaterials evaluation.

Aggregation Analysis System for Biopharmaceuticals

180° Peeling Test for Adhesive Tapes

The Aggregates Sizer aggregation analysis system enables the quantitative evaluation of particle amounts in the 0.1 μm to 10 μm range as a concentration (units: μg/mL or particles/mL). Aggregations of biopharmaceuticals can be categorized into 4 ranges: nanometer (<100 nm), submicrometer (100 nm to 1 μm), subvisible (1 to 100 μm), and visible (>100 μm), according to their particle size. Until now, particles in the submicrometer to subvisible portion of this range (100 nm to 10 μm) were generally measured by combining multiple methods.

Observation of Organic Specimens with an X-Ray CT System and Creation of 3D Printed Molds

Observation of Organic Things with X-Ray CT System and Molding created with 3D printer

The inspeXio SMX-100CT system has a micro focus X-ray generator (max.100kV) and high sensitive image intensifier, making this system useful for the observation of soft materials (resin, bone etc.). The internal structures of small insects such as internal muscles and nerves can be observed nondestructively by CT imaging.

Observation of a Mouse Femur Using an X-Ray CT System

At universities, pharmaceutical manufacturing companies and in other research fields, a variety of research using experimental animals is being conducted, including research into bone diseases, as well as drug administration evaluations, and fat measurements for metabolic research. The main experimental animals are rats, mice, and rabbits. In this context, X-ray CT systems are often used to observe and analyze the bones of small animals, and for research on the teeth of humans and small animals. Observations of small animals consists of in vivo CT imaging of living animals, and in vitro CT imaging of dead animals and excised parts. This article introduces imaging (in vitro) CT data from mouse femurs, taken using the inspeXio SMX-100CT, as well as analytical results from 3-dimensional analysis software utilizing the CT data.
