How to solve the huge deflection of acrylic products?
1, first and foremost, is the use of deflection theory, but this method is quite complex, in many case applications, thermoplastic material formula is not all can be applied now.
2, followed by the method of choice, that is, the use of a relatively simple theory of small deflection, the first consideration of the possible deflection, the extent of its tolerance can be limited, rather than from the stress point of view to consider the design, Is caused by the wind load. This method has the added advantage: even in the wind load, the logo can also maintain a good appearance, not easy to be blown off by the installation frame.
3, the rules taken are: the final degree of curvature can not exceed the thickness of the material. Because in such a low bending state, the material under the surface tension of the film stress is small.
