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 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

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 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 obtained from numerical simulation showed that the value of the peak stressSeqvincreased first and then decreased evidently when the notch depth increased from 2 mm to 8 mm. Comparing the results with that from Izod impact test, it is found that the response time retarded about 0.02 ms and the peak value of the stressSeqvdecreased evidently under the Charpy impact test. The results from the experiments showed that the effect of notch depth on the impact energy absorbed by unit area of joint is as same as that from the Izod impact test.

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 results obtained show that the highest value of the stressSeqvalmost higher than the yield strength of the adherend reached within about 0.1 ms. The contour diagram of the stressSeqvis 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 theSeqvin adhesive increases first and then decreased when the action of the impact was over. The stressSeqvin both ends of the specimen kept to a relative lower value during impact procedure.

The effect of the adhesive thickness on the impact toughness of the adhesively bonded steel joint under impact loading is studied using the experimental method. The results obtained show that the impact toughness increases when the adhesive thickness increased then it decrease as the adhesive thickness increase. When the curing time is set as a constant, the higher the curing temperature is, the lower the impact toughness of the joint. The optimum thickness of the adhesive layer for the specimen of impact toughness test cured at 60 C for 1 h is 0.6 mm and it is 0.4 mm to 0.6 mm for the specimen cured 1 h at temperature of 90 C or higher than it. It is recommended using the notched specimen to decrease the testing deviation.

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.

The Impact

In high-speed gear drive and power transmission, system impact failure mode always occurs due to the sudden impact and shock loading during the system in running. Therefore, study on the amount of impact energy that can be absorbed by a gear is vital. Impact test equipment has been designed and modelled for the purpose to study the impact energy on gear tooth. This paper mainly focused on Finite Element Analysis (FEA) of impact energy that occurred during simulation involving the impact test equipment modelling. The simulation was conducted using Abaqus software on critical parts of the test equipment to simulate the impact event and generate impact data for analysis. The load cell in the model was assumed to be free fall at a certain height which gives impact load to the test gear. Three different type of material for the test gear were set up in this simulation. Results from the simulation show that each material possesses different impact energy characteristic. Impact energy values increased along with the height of load drop. AISI 1040 were found to be the toughest material at 3.0m drop that could withstand up to 44.87N.m of impact energy. These data will be used to validate data in physical experiments in further study.

The paper presents the static strength of adhesively bonded steel joints aged in deionized water at a temperature of 60°C for 15 days at various adhesive thicknesses from 0.1 mm to 0.5 mm. Water uptake and the bulk adhesive tensile properties after aged in the same environment as the joints were also presented. It has been shown that water diffusion into the adhesive is non Fickian. The absorbed water in the adhesive significantly decreases the mechanical properties and it affects the static strength of the bonded steel joints. The effect of water is shown to be significant when the adhesive thickness is thicker than 0.2 mm as the static strength decreases sharply. This information is useful when designing the adhesive joints using thick adhesive layer exposed in moist environment.
