Tension Experiments

The mechanics problems can drastically compromise device performance and reliability. To solve these problems, there is a need to develop a fundamental understanding of mechanical behaviors of microstructures in MEMS. Also the increasing use of small micromechanical devices and advanced sensors has led to concern about the failure modes and reliability of these structures. In this paper a micro sample tension machine is made and using it one kind of micro sample fabricated with micromachining is tested. The tension experiments of the micro sample are done under different current to get the comparing data. The experiments yield reasonable and reproducible data. It is shown apparent plastic deformation of the micro sample happens under tension force. Mechanical behavior of the micro sample is distinguished to that of the sample with macro dimension. Micro size effect can be concluded about the micro sample under tension. Under different currents the elastic modulus and the tensile strength of the micro sample decrease with the current increasing. The relationships between them are gotten through experiment. The reliable designing parameters of the material are gained. The glaring outcome is that the uses of the material are depended highly on processing and fabrication techniques. The fabrication techniques can be developed and make the material both practical and reliable.

The Comparative Study

In order to obtain the tensile strength of the C40 concrete accurately, the comparative study between Brazilian disc splitting experiment and the direct tensile experiment is conducted with a self-modified tensile loading device. The study shows that the tensile strength observed from the direct tensile experiments (3.64MPa) is lower than that from the experiments (5.44MPa). A comprehensive analysis of experimental results is conducted focusing on the perspectives of the specimen failure forms, energy dissipation, the correlation of strength and hydrostatic pressure etc. The study suggests that the main reasons for the differences between Brazilian tensile experimental strength and direct tensile experimental strength include the surface energy required by the specimen destruction, the bond strength between the aggregate, the hydrostatic pressure in the process of loading and other factors.
