The springback is mainly an elastic deformation which occurs after sheet metal forming processes. This paper analyzed the mechanism of deep drawing springback of sheet metal forming, and the springback compensation was studied. Based on this, taking the stiffener parts of auto as an example, the paper analyzed the trend and distribution of springback and its distribution under different conditions...
The design rationale, synthesis, and characteristics of organic chromophores exhibiting very large EO response is presented along with new methodologies to assembled them in a noncentrosymmetric fashion.
On-line analytical processing (OLAP) has become a very useful tool in decision support systems built on data warehouses. Relational OLAP (ROLAP) and multidimensional OLAP (MOLAP) are two popular approaches for building OLAP systems. These two approaches have very different performance characteristics: MOLAP has good query performance but bad space efficiency, while ROLAP can be built on mature RDBMS...
