The grain growth behavior of spray-formed Al-70wt.%Si alloys was studied in the semi-solid state. The specimens were isothermally heat-treated at various temper
This paper investigates the characteristics of reduction of the lateral vibration by use of a Tuned Mass Damper(TMD) for offshore jacket platforms under impact
A two-dimensional smeared crack model for reinforced concrete members is presented. Special emphasis is placedon the bond between concrete and reinforcement as
The geochemical features of REE were studied by comparing the copper ore with the skarn, the diorite and the stratum, to trace the source of metallogenic materi
Ag+-exchanged resins are prepared and studied for ethylene/ethane separation by adsorption. OnAg+-exchanged S9, at 25℃ and 0.1013 MPa, the equilibrium adsorbed
A numerical model reflecting the real physical processes well has been developed to predict the coarsening manner of the second phase droplets and the microstru
The sea ice is idealized as an elastic-brittle material. When an ice sheet moves toward a structure, the dynamic in-teraction between ice and the structure is a
Based on the principle of Tuned Mass Damper (TMD),the test of a new quake-reduction system was investigated.The main structure of the system is connected with t
The capability of several types of flat PDC cutters to withstand combined loads were tested and evaluated by the impact and cutting of single PDC cutter on gran
