This paper introduces a new type of rock wool color steel sandwich which is produced by Anhui sambo steel co.,Ltd. The thermal performance analysis of this kind of sandwich is conducted through the finite element software ANSYS in this paper, which reveal the widespread existence of cold bridge phenomenon. And this paper also propose several new ideas on how to reduce the cold bridge condensation of interior wall panels of building.

Assembly Operations

The efficient codes can take an advantage of multiple threads and/or processing nodes to partition a work that can be processed concurrently. This can reduce the overall run-time or make the solution of a large problem feasible. This paper deals with evaluation of different parallelization strategies of assembly operations for global vectors and matrices, which are one of the critical operations in any finite element software. Different assembly strategies for systems with a shared memory model are proposed and evaluated, using Open Multi-Processing (OpenMP), Portable Operating System Interface (POSIX), and C++11 Threads. The considered strategies are based on simple synchronization directives, various block locking algorithms and, finally, on smart locking free processing based on a colouring algorithm. The different strategies were implemented in a free finite element code with object-oriented architecture OOFEM [1].

A novel flexure hinge named right circular corner filleted half hybrid flexure hinge was advanced. Based on the Castigliano second theorem, the compliance formulas of the novel flexure hinge were formulated. The theoretical calculations and the finite element simulations were performed simultaneously, the similar results were obtained which indicated the correctness of the compliance formulas. The influence of the geometric parameters of the novel flexure hinge on its performance was analysed. Compared with right circular corner filleted double hybrid flexure hinge, the compliance and sensitivity to the load of the novel half hybrid flexure hinge were better than that of the right circular corner filleted double hybrid flexure hinge. All of the above analysis results indicated the novel flexure hinge are more suitable for application in the compact structure and large displacement.
