Qh. Qin, TRANSIENT PLATE-BENDING ANALYSIS BY HYBRID TREFFTZ ELEMENT APPROACH, Communications in numerical methods in engineering, 12(10), 1996, pp. 609-616
The paper presents a hybrid Trefftz (HT) element approach for the nume
rical solution of transient plate bending problems. In the proposed me
thod, the dynamic plate equation is first discretized with respect to
time and then the resulting set of elliptic equations is solved by the
corresponding time independent hybrid Trefftz element approach. Two e
xamples are considered to assess the effectiveness of the numerical me
thod.
