【Abstract】 Presented the Trefftz type boundary solution method for analysis of the moderately thick plate bending problems. A new type of “locking phenomenon” which is caused by the overflow of Trefftz function has been observed and a so called variable reducing procedure for eliminating such a locking problem is proposed.更多还原
