In a linear static study, which quantity does the solver calculate first, with the remaining results derived from it?
Correct answer: A - Nodal displacements, from which strains and then stresses are derived
A static study of a ductile steel bracket reports a maximum von Mises stress of 320 MPa. The assigned material has a yield strength of 250 MPa and an ultimate tensile strength of 400 MPa. Which statement is the most complete interpretation?
Correct answer: B - The factor of safety is 0.78, and the linear static result is no longer valid where yielding occurs
In a linear static study, replacing a part's material with a higher-yield-strength steel of the same elastic modulus will reduce the part's maximum displacement under the same load.
Correct answer: B - False
A part is cut in half on its plane of symmetry to reduce solve time. In the full model a 1,200 N force acts on a face that the symmetry plane bisects exactly. What force should be applied to that face in the half model?
Correct answer: C - 600 N, because only half of the loaded face remains in the model
In SOLIDWORKS Simulation, how many nodes does a single high-quality (second-order) solid tetrahedral element have, and how many degrees of freedom does each of those nodes carry?
Correct answer: B - 10 nodes, with 3 degrees of freedom at each node
In the Force PropertyManager, three separate faces are selected and a value of 40 lbf is entered with the 'Per item' option active. What total force does SOLIDWORKS Simulation apply to the model?
Correct answer: D - 120 lbf
Two components in a new assembly static study have touching faces. No contact sets, local interactions, or component interactions have been defined. How will SOLIDWORKS Simulation treat those touching faces?
Correct answer: D - As Bonded, so the components behave as a single continuous body
A stress concentration around a small fillet needs a finer mesh, but the model already takes a long time to solve. Which approach is the most efficient?
Correct answer: C - Apply a mesh control to the fillet faces to refine only that region
A hands-on question asks for the displacement in the global Y direction at one specified vertex. The candidate runs the study and reports the maximum value shown on the default displacement plot. Why is this answer likely to be marked wrong?
Correct answer: C - The default plot shows URES, the resultant magnitude, not the signed Y component
A gravity load is added to a static study, but the resulting displacement is identical to the study run without it. What is the most likely explanation?
Correct answer: A - The material assigned to that body has no mass density defined
