Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature being described, example is served only for explaining this utility model, is not intended to limit scope of the present utility model.
As Figure 1-3, a kind of Mixed Mode Fracture experiment loading unit, it is oppositely arranged including about a pair and coplanar C type arc plate 1, the central angle of described C type arc plate 1 is 90 °.Described C type arc plate 1 is provided with the arc chute 11 that bolt is fixed on testing machine, on described C type arc plate 1, the position of corresponding described arc chute 11 is provided with the angle index 12 of experiment machine power load and specimen crack face 32 normal direction angle, bolt is fixed to the diverse location of arc chute 11, it may be achieved the adjustment of experiment machine power load and specimen crack face 32 normal direction angle.The inwall of described C type arc plate 1 has also been relatively fixed cross fixture 2 up and down, it is preferred that: described cross fixture 2 is welded on the inwall of described C type arc plate 1.
Described cross fixture 2 is provided with the cross bath blocking test specimen 3, described cross bath includes the first vertical clip slot 23 and the second clip slot 24 that intersect, and described cross fixture 2 surface segmentation is become four protruding columns 21 by this cross bath, column is equipped with two orthogonal and corresponding with the connecting hole 31 on test specimen 3 fixing holes 22 of axis at each described, in described fixing hole 22, is provided with connection test specimen 3 and is fixed in the bolt in described cross bath.Test specimen 3 first snaps in cross bath connect again through bolt, it may be achieved the location of test specimen 3.
Introduce this utility model separately below and realize I/II type and the process of I/III type combined rupture test:
As shown in Figure 4, by adjusting the spatial relation between sample 3 and charger, it is stuck in the first clip slot 23 by test specimen 3 and can realize I+II Mixed Mode Fracture test loads.When test specimen 3 is stuck in the first clip slot 23, if experiment machine power load and specimen crack face 32 normal direction angle are α, when α=0 °, loading direction is vertical with direction of check, is I type opening mode load-up condition, when α=90 °, loading direction is parallel with crackle, is II type sliding mode load-up condition, when 0 ° < α < 90 °, loading direction is angled with crackle, is I+II compound load-up condition.
As it is shown in figure 5, by adjusting the spatial relation between sample 3 and charger, be stuck in the second clip slot 24 by test specimen 3 and can realize I+III Mixed Mode Fracture test load.When test specimen 3 is stuck in the second clip slot 24, if power load and sample crack surface normal direction angle are β, when β=0 °, loading direction is vertical with direction of check, is I type opening mode load-up condition, when β=90 °, loading direction is vertical with crack surface normal direction, is III type tearing mode load-up condition, when 0 ° < β < 90 °, loading direction is angled with crack surface normal direction, is I+III compound load-up condition.
