Calculation of bending performance 1. Calculation of bending performance our products include 1seiries, 3series, 5series and 8series of Aluminium Sheet and aluminium checkered plate The alloys include a1050 a1060 a1100 a3003 a3004 a3105 a5005 a5052 a5754 a5083 a6061 and a8011. The thickness of the aluminium sheets are from 0.2mm to 200mm.The width are from 500mm to 2200mm.The length are from 500mm to 9000mm.We can also produce the aluminium sheets according to customers' verious special demands.The aluminium sheets are used to lighting ,solar reflective film,building exterior, interior dectoration,furniture, elevators,signage, automotive interior and exterior decoration, household appliances and so on.The checkered plates are used in air-condition, car, platform, pipeline, screen framework,the table leg,trim strip,handles and so on.

1) Calculation of bending strength:
Tt=3PL/2bh2
Where: бt—bending strength, MPa; P—bending load on the specimen, MN; L-span, mm;
B-sample width, mm; h-sample thickness, mm.
2) Calculation of flexural modulus:
Et=(L3/4bh3)(P/Y)
Where: Et-bending elastic modulus, MPa; L-span, mm; b-sample width, mm; h-sample thickness, mm;
P-load at the linear portion of the load-deflection curve, N; Y-load corresponding deflection, mm.
3. Influencing factors of test results
The state adjustment of the sample, the test environment, and the bending speed have a certain influence on the bending performance. In addition, the measurement of the sample size, the adjustment of the test span, the line contact and vertical condition of the indenter and the sample, and the adjustment of the zero point of the deflection value all have certain influence on the test results.
4. Unit
The unit of bending strength is MPa, and the unit of bending elastic modulus is MPa or GPa.
