Abstract: Drying shrinkage loads are converted into the equivalent temperture,using the model of composite material mechanical analysised layer stresses and interlaminar stresses of the shear wall under the influence of temperture load stress,combined with wind load and weight ,acquired the thermal insulation layer’s stress effect under the combined effect. According the failure criterion of material and adhesive surface, to determined the cracking mechanism and crack control of aerated concrete thermal insulation layer.

Abstract: An interfacial shearing and peeling stress model is proposed to account for different uniform temperatures and thickness wise linear temperature gradients in the layers. This upgraded model can be viewed as a more generic form to determine interfacial stresses under different temperature conditions in a bi-layered assembly. The selected shearing and peeling stress results are presented for the case of die and die attach as commonly seen in electronic packaging. The obtained results can be useful in interfacial stress evaluations and physical design of bi-material assemblies, which are used in microelectronics and photonic applications.

Abstract: Spew fillet is common in co-cured composite single lap joint. It plays an important role in the safety of the joint. But few attentions were paid to the subject in former investigations. In this paper, co-cured composite single lap joints with spew fillets under static tensile load were investigated numerically using the commercial finite element code ANSYS. The submodeling technique was employed to overcome the problem caused by extra aspect ratio of elements. The computation results indicated that the existence of spew fillets will not change the possible failure location, but will improve the anti-failure performance of single lap joint.
