Strength is considered in terms of compressive strength, tensile strength, and shear strength, namely the limit states of compressive stress, tensile stress and shear stress, respectively. The effects of [[dynamic]] loading is probably the most important [[practical]] part of the strength of materials, especially the problem of [[fatigue]]. Repeated loading often initiates brittle cracks, which grow slowly until failure occurs. | Strength is considered in terms of compressive strength, tensile strength, and shear strength, namely the limit states of compressive stress, tensile stress and shear stress, respectively.
