Stimuli-responsive hydrogels are becoming increasingly important for controlled drug delivery, biosensing, and tissue engineering. It would be much advantageous for intelligent hydrogels if they exhibit superior mechanical performances.

This paper studies on deformation parameters through plate loading test (PLT) of some different areas plate, Standard penetration test (SPT) and laboratory test in Dynamic Compaction (DC) desert foundation in Inner Mongolia based on engineering practice. According to the result of experiment, it established relationships between deformation modulus and SPT counts values, compression modulus and SPT counts values, compression modulus and dry density, that can gain experience for detection of DC in similar site.

Collaborative design is a significant method to improve the efficiency of complex product development. In order to reinforce the update and synchronize mechanism of the collaborative working environment, relational design techniques are studied. Taking airplane wing as an example, the relations in product design, manufacturing and measurement stages are analyzed and classified into three types: datum reference relation, parameter relation and non-geometric relation. Then the creation and update methods of the relations of each type are discussed respectively, and they are summarized to a uniform user operation pattern. Finally, a relational design tool is developed and applied in a case study, which validates the feasibility of our methods.
