Hi, i am doing FEA on a access cover and i am not sure if i am doing it right.i am jus begnieer in simulation ,any help would be much appreciated.
boundry conditions : access cover will be sitting in a pit.
material : grade 250 steel
anaysis : non linear static or dynamic (not sure)
these access covers usually tested by a hydrualic press where they put load in the centre on a 240x240 block. the load applied on a rate of 5kn/sec.they do 5 repetions of this load and it depends on the load class that how much load should be applied.deflection and permanent set is important to assess if the access cover will pass or fail in the actual testing.these covers are tested according to AS 3996 STANDARD.
class A 10kn
class b 80kn
class c 150kn
class d 210kn
please anybody can help me to get this right
