Toughness metal
WebOct 26, 2024 · As mentioned above, tungsten is the strongest of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal known to shatter on impact. On the other hand, Titanium has a tensile strength of 63,000 psi. When looking at titanium’s density, with a pound-for-pound comparison, it beats tungsten. WebInternal imperfections have a size of 0.0015 mm. A steel plate, which has a fracture toughness in a plane strain state of 83 MPavm, is alternately loaded in tension at 750 MPa and in compression at 20 MPa. The plate must survive 15 years with the stress applied at a frequency of once every 3 min. Calculate the constant C of the material if n=2.8 .
