← ScienceWhich risk increases when pulsed electromagnetic forming exceeds limits?
A)Workpiece material reaching tensile fracture✓
B)Capacitor bank parametric inductance rise
C)Transformer core harmonic resonance formation
D)Oscillator circuit parasitic capacitance increase
💡 Explanation
Exceeding forming limits produces excessive electromagnetic forces; therefore magnetostriction's effect leads to rapid deformation exceeding ultimate tensile strength because it induces crack initiation and propagation, rather than transformer core resonance at different frequencies.
