[ 1 ] - بررسی عددی رفتار ورق‌های کامپوزیتی چندلایه فلز- الیاف تحت ضربه کم سرعت

In this article, low velocity impact behavior of fiber metal laminate (FML) composite plates is investigated under three different impact energies (12.7 J, 16.3 J and 24.2 J). Here, three modeling techniques are used. In one of the models the inter-laminar damage is neglected (model without delamination) and in other two models this damage is simulated using cohesive element and cohesive surfac...

[ 2 ] - Nonlinear Modeling of Bolted Lap Jointed Structure with Large Amplitude Vibration of Timoshenko Beams

This paper aims at investigating the nonlinear behavior of a system which is consisting of two free-free beams which are connected by a nonlinear joint. The nonlinear system is modelled as an in-extensional beam with Timoshenko beam theory. In addition, large amplitude vibration assumption is taken into account in order to obtain exact results. The nonlinear assumption in the system necessities...
