VHB Tape Fail

Part of what I am doing on the lunar lander dwelling project; building a tiny house using boat construction, is to test the limits of many techniques and products. I took the VHB tape past its limit.
I tried to use it to attach an acrylic shower door without any fasteners; a worthy goal.
While the VHB tape is amazingly strong, it has limits. Its weakness as I understand it, is long duration loading, while depending on peel strength. The shower door provided that.  It’s tepid resisting the energy of initiation, followed by energy of propagation, made it fail.

In the picture, the VHB tape attaches both the hinge and the angle brackets.  Both failed after a while.
On a window, peel strength would not even enter into it. I’m always curious about where the real world limits are.
