When one dimension of structure is much longer than the others, the strain in that direction can be negligible. Buckling is the critical failure mode when Euler beams are subjected to very large compressive stress than the yield strength. Fatigue failure of the structure occurs due to the sudden impact load. The reliability of products always decreases with respect to time or cycles with constant failure rate. For thin-walled pressure vessels, the stresses in the thickness direction can be negligible. The stress concentration occurs due to the geometric discontinuity but does not depend on the type of loads. Based on the fracture mechanics theory, the structural failure always occurs due to the presence of cracks or defects. In general, failure of ductile materials occurs in the principle plane due to the principle stresses. Ultimate strengths of brittle materials are always smaller than those of ductile materials since the magnitudes of stresses near the crack tip of brittle materials are much larger than those for ductile materials. The fatigue life decreases with increasing mean stress value.

The theoretical failure strength is significantly higher than the empirical failure strength of polycrystalline materials, even when they are highly polished because: a) Polycrystalline materials have little or no capacity for plastic deformation, so they have lower failure stresses b) Plastic deformation in polycrystalline materials adsorbs energy which reduces their failure strength c)The energy needed to break the atomic bonds in crystal lattices is lower in polycrystalline materials as compared to in single crystals d)Polycrystalline materials contain internal discontinuities
19) Indicate the incorrect expression for plastic deformation of metallic materials: a) The level of the yield strength does not indicate if necking occurs after a small amount of homogeneous deformation or after a large amount (in other words, if the start of necking is delayed or not). b) Greater strain hardening exponent means an earlier 'necking'. c) If 'n' and 'm' parameters are greater the larger the homogeneous plastic deformation range. d) When plastic deformation progresses sufficiently, the negative contribution to the strain hardening of the metal due to local adiabatic heating starts the local plastic deformation.
