Studying the deformation and fracture properties of soft materials can not only provide insight into the physical mechanisms underlying their superior properties and functions but also benefit the design and fabrication of rubberlike materials.
Increasing applications of rubberlike materials make it important to maintain the reliability and stability of these materials.
Experimental analysis on fracture problem of polymeric materials has been processed by the authors [9].

Yet, developing implant materials is inseparable with the choice of suitable material.
All of the materials are considered isotropic and linearly elastic.

The 35th volume of the journal "Advanced Engineering Forum" includes peer-reviewed manuscripts describing the engineering solutions and results of research dealing with actual problems in applied materials science, mechanical engineering, building engineering, applied mechanics, power engineering and engineering management.

It showed that all human built materials (concrete cement ground and pavement ground) has some time delay during temperature decrease (points 1, 3 and 5).
Compared with human built materials (points 1-5), no time delay was found on point 6 (grass surface).
Conclusions This work studied on the performance of kinds of materials on outdoor surface temperature.

Compared three cases with various metal materials, temperature differences between metal spheres and fluids are decreased because the thermal conductivity of three metal materials of copper, aluminum and steel decrease gradually.
The thermal conductivity of metal spheres had no significant effect on the flow in porous metal materials.
