Effect of Primer's Elastic Modulus on the Response of Multi Layer Bonded Steel Butt Joint under Izod Impact Test

Article Preview

Abstract:

The effect of the elastic modulus of the adhesive for primer on the impact response of the steel butt joint bonded by multi-layer under the Izod impact test is investigated using the elasto-plastic finite element method (FEM). The results obtained from numerical simulation show that both the elastic strain and plastic strain occurred at the point 0.5 mm away from the upper or lower surface after a certain time is increased significantly when the elastic modulus of the primer is decreased from 2.875 GPa to 0.825 GPa. The absolute value of the stress Sx response at these to nodes is decreased when the elastic modulus of the primer is decreased. The value of the stress Seqv is the highest one after 0.1 ms at the points 0.5 mm away from the upper or lower surface when the butt joint is bonded by the multi layer consisted of Epoxy-Phenolic-Epoxy adhesives.
