The critical value at which crack extension occurs is called
Stress intensity factor is the critical value of stress at which crack extension occurs.
The critical value at which crack extension occurs is called
Fracture toughness does not depend upon geometry of the part containing crack
How many modes are there for crack propagation?
A curved beam has neutral axis is curved while loaded and straight when unloaded.
A curved beam with eccentricity 0.02D is loaded with 1kN.Centroidal radius=4D and inner and outer radii are 3.5D and 4.5D respectively. Area of cross section is 0.8D². Find the dimension D if allowable stress is 110N/mm².Considering only bending stress.
A curved beam with eccentricity 0.02D is loaded with 1kN.Centroidal radius=4D and inner and outer radii are 3.5D and 4.5D respectively. Area of cross section is 0.8D². Find the dimension D if allowable stress is 110N/mm² and considering only direct tensile stress.
The bending stress in a straight beam varies linearly with the distance from neural axis like that in a curved beam.
A curved beam with eccentricity 0.02D is loaded with 1kN.Centroidal radius=4D and inner and outer radii are 3.5D and 4.5D respectively. Area of cross section is 0.8D². Find the dimension D if allowable stress is 110N/mm² and considering combined effect of direct stress and bending stress.
