The finite element analysis is adopted in this primary study. Using the Tsai-Wu criterion and delamination criterion, the stacking sequence [45\/04<\/sub>\/-454<\/sub>\/904<\/sub>]s<\/sub> is the final optimal design for the wheelchair frame. On the contrary, the uni-directional laminates, i.e. [9013<\/sub>]s<\/sub>, [4513<\/sub>]s<\/sub> and [-4513<\/sub>]s<\/sub>, are bad designs due to the higher failure indexes.<\/p>\r\n","references":"[1]\tDaniel IM, Ishai O.
