studied using the finite element method (FEM) software ANSYS. The results obtained show that the highest value of the stress <i>Seqv</i> almost higher than the yield strength of the adherend reached within about 0.1 ms. The contour diagram of the stress <i>Seqv</i> is symmetrical to the axis along the half height of the specimen both in whole adhesively bonded steel butt joint and the adhesive layer. The peak value of the <i>Seqv</i> in adhesive increases first and then decreased when the action of the impact was over. The stress <i>Seqv</i> in both ends of the specimen kept to a relative lower value during impact procedure. </div> <div> <a data-readmore="{ block: '#abstractTextBlock357158', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 542 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.488-489.538">Effect of Notch Depth on the Adhesively Bonded Steel Butt-Joint under Charpy Impact Test</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Min You, Mei Li, Jian Li Li, Kai Liu, Ya Lan Zhao </div> </div> <div id="abstractTextBlock357155" class="volume-info volume-info-text volume-info-description"> Abstract: The effect of the notch depth on the impact properties of the adhesively bonded steel butt joint under the Charpy impact test is studied using both the finite element method (FEM) and experimental method.

The results from the numerical simulation showed that the stress is varied a little when the joints with a couple of 4 mm long metal block adhered to both ends of the over lap or with a couple of adhesive fillet. Compared to the joint without the metal block, it is advantageous of reducing the peak stress in the adhesive layer near the ends of the lap zone in adhesively bonded single lap steel joints but its effect is less than that of the joint with a couple of adhesive fillet. There is no evidential difference in the effects between the steel and aluminum block. </div> <div> <a data-readmore="{ block: '#abstractTextBlock250575', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 243 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.644.193">Numerical Analysis of Impact Velocity on the Responses of Adhesively Bonded Steel Butt Joint with Material Properties</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Min You, Kai Liu, Hai Zhou Yu, Ling Wu, Mei Li </div> </div> <div id="abstractTextBlock250553" class="volume-info volume-info-text volume-info-description"> Abstract: The effect of the impact velocity on the responses of the adhesively bonded steel butt joint during Izod impact test and the failure procedure is studied using the finite element method software ABAQUS.

The peak value of the Seqv in element 1 increases first and then decreased when the impact velocity reached 4.2 m/s. When the impact velocity is higher than 6.2 m/s, the peak value of the Seqv increased again as the impact velocity increased until 10.2 m/s.

The results obtained show that the impact toughness decreases when the shock temperature increased. When the curing time, temperature as well as the open assembly time was set as constant, the higher the shock temperature is, the lower the impact toughness of the joint. Comparing to the Charpy impact test, the Izod impact test is more sensitive to the shock temperature. When the shock temperature is set at a value not less than 300 C, the impact toughness measured is nearly the same as zero due to decomposition, carbonization and volatilization of the adhesive. </div> <div> <a data-readmore="{ block: '#abstractTextBlock226792', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 2096 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.166-169.2896">Effect of Temperature on the Thermal Stress in the Single Lap Joint</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Min You, Cun Jun Chen, Hai Zhou Yu, Chun Zhi Mei, Mei Li </div> </div> <div id="abstractTextBlock190058" class="volume-info volume-info-text volume-info-description"> Abstract: The effect of the thermal shock temperature on the thermal stress distributed in the adhesively bonded steel single lap steel joint under a 10 s thermal shock was investigated using elasto-plastic finite element method (FEM).
