摘要

An adaptive technique of the h-version for vibration problems, utilizing a new error indicator and mesh refinement strategy, is proposed. It is based on improvement of the eigenmodes by Superconvergent Patch Recovery. A modification of the termination criterion of the adaptive strategy is proposed. The error indicator is tested by a numerical example and discussed. The adaptive technique is tested by some engineenng examples.
