The wrench is 5 mm thick. A total load of 264 Newtons is uniformly distributed over the top surface located on the horizontal plane in the right of the wrench. The inside surfaces of the left hexagon are fixed to simulate the bolt tightening. Determine the von Mises stresses and maximum deflection under the given distributed load and boundary conditions. Check the convergence of your analysis. Step 1 Using Pro ENGINEER create a bicycle wrench as shown in the Figure below. Make sure the units is in mmNs. Add the two hexagon cut-outs on the left and right ends of the wrench 1 Step 2 Transfer the model to Integrated Mode of Pro MECHANICA. Three algorithms that can be chosen 1. Quick Check No convergence Pro MECHANICA performs a single pass analysis with uniform p 3. This method is used to verify if your analysis has been set up correctly. 2. Single-Pass Adaptive Pro MECHANICA runs a first pass at p 3 and determines a local estimate of stress error. Using this error estimate Pro MECHANICA determines a new p-order distribution and performs a final pass. 3. Multi-Pass Adaptive When you run a design study the Structure engine performs calculations and increases the polynomial order p-order for each element edge until the convergence criteria is satisfied. An analysis converges when the difference in the results of the results of the current and previous passes are within the percentage you specify under Convergence.
