Introduction Mechanics of materials is a science based on experiment, "experimental" teaching occupies a special position in the whole education in mechanics of materials in the teaching process, for the coordinated development of students' knowledge, ability, thinking and quality plays a vital role.
Therefore, the material mechanics experiment teaching is not only an important practical teaching link in the cultivation of innovative talents in mechanical major, but also cultivate nearly limitation of specialty (environment, control, materials and other professional) to improve students' experimental ability, an important practical teaching link of practice and innovation capability.

Periodicity and mismatch of materials in PC results in the phononic band gaps, where the propagation of elastic waves and vibrations is forbidden.
The range of the mass density of solid materials is 1000 kg m-3≤ρ≤20000 kg m-3, so the range of the mass density ratio is 0.05≤ρ1/ρ2≤20.

The performance of concrete materials under high temperature is more complex than that under room temperature.
This paper, by analyzing the mechanical property of concrete materials under high temperature(fire), probes into the changing law of the concrete materials' compressive strength under different temperatures (16 ˚C-800 ˚C) and different static placing time and makes a comparison on the concrete materials' strength between natural cooling and water cooling; illustrates the relationships of concrete materials' compressive strength and temperature, holding time and cooling and other factors under high temperature(fire).
Cool the above-mentioned concrete specimens and stand for a certain temperature environment for some time, and then have the compressive strength test of concrete materials; focus on the regular pattern of concrete strength influenced by temperature and cooling method.
