The Impact

The effect of the notch depth on the impact toughness of the adhesively bonded steel butt joint under Izod impact test is studied using both the finite element method and experimental method. The results obtained from numerical simulation showed that the response time with the peak stress Seqv occurred becomes little longer when the notch depth increased from 2 mm to 8 mm. And a negative longitudinal stress occurred when there is an 8 mm depth notch which might be beneficial to subject impact load. The results from the experiments showed that the effect of notch depth is evidently on the Izod impact properties. The impact energy absorbed by unit area of joint is increased as the notch depth increase

Peak Value

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 results obtained show that the failure time of the element becomes little shorter when the impact velocity increased from 3.2 m/s to 10.2 m/s. 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. It is recommended that the impact velocity of 3.2 m/s or 5.2 m/s is suitable for Izod impact test for the adhesively bonded steel butt joint.

The Impact

The effect of the adhesive thickness on the impact toughness 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 results obtained show that the time with the peak stress Seqv occurred is corresponding to the element failure. And much higher peak stress might be subjected by the element near the bottom of the joint under impact load. The failure time of the element becomes little longer when the adhesive layer thickness increased from 0.1 mm to 0.4 mm. But the peak value of the Seqv decreases and the damage limit of the strain increased evidently as the adhesive thickness increased from 0.2 mm to 0.4 mm.

The Impact

The effect of the shock temperature and time on the impact toughness of the adhesively bonded steel butt joint under Charpy or Izod impact test is studied using the experimental method. 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.

The Impact

This paper compares transportation mockup cask impact test results onto real surfaces with FEA numerical simulation results. The impact test results are from a series of cask impact tests that were conducted by Sandia National Laboratories (Gonzales 1987). The Sandia tests were conducted with a half-scale instrumented cask mockup impacting an essentially unyielding surface, in-situ soil, concrete runways, and concrete highways. The cask numerical simulations with these same surfaces are conducted with ABAQUS/Explicit, Version 5.8, The results are then compared and evaluated to access the viability of using numerical simulation to predict the impact behavior of transportation casks under hypothetical accident conditions.

This research aim to investigate the effect of graphite loadings in unsaturated polyester (UPE) / acrylated epoxidized palm oil (AEPO) blend resin. The modification of epoxidized palm oil (EPO) to AEPO was carried out using acrylation process and further blended with synthetic UPE resin. Graphite powder was added at 0.03, 0.05 and 0.1 phr into the UPE/AEPO blend resin and cured in an oven at 100 °C and 160 °C. FTIR spectrums showed the disappearance of oxirane ring and existence of carbon double bond indicating successful of AEPO synthesis process. Tensile and Izod impact test revealed that, graphite showed different effects to neat UPE and UPE/AEPO blend resin. In neat UPE, graphite significantly improved the stiffness properties at 0.1 phr additions. However in UPE/AEPO blend resin, the toughness properties were improved with increased graphite loadings.

The Impact

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.
