You will not be able to bend laminated ali sheet with out making a mess of the top radious even with heat. The heat or anealing to call it by its proper name will need to be about 300 'c plus and will distroy the the laminating compound between the sheets. The top sheet will need to strech 1.5-1.75 the times of the bottom sheet and thats why it cracks it just receives to much tension going round a larger radious than the bottom sheet. Ali sheet comes in about 4-5 different grades some are cheap and soft easy to bend and the more expensive is for structural work. If you are planning on using any ali and you don't know what it is or what grade it is I'd say only use it as a covering not some thing structural like the floor. I worked in sheet metal shop for 5 years learning as I went and ali is not like steel, if you use the wrong stuff in the wrong place it will tear like tissue paper.
