I. Residual Stresses and Their Measurement
Residual (locked-in) stresses in a structural material or component are those stresses that exist in the object without (and usually prior to) the application of any service or other external loads. Manufacturing processes are the most common causes of residual stress. Virtually all manufacturing and fabricating processes — casting, welding, machining, molding, heat treatment, etc. — introduce ...
متن کاملDrying patterns: Sensitivity to residual stresses.
Volume alteration in solid materials is a common cause of material failure. Here we investigate the crack formation in thin elastic layers attached to a substrate. We show that small variations in the volume contraction and substrate restraint can produce widely different crack patterns ranging from spirals to complex hierarchical networks. The networks are formed when there is no prevailing gr...
متن کاملRevision Residual Stresses in Oscillating Thoracic Arteries Reduce Circumferential Stresses and Stress Gradients Residual Stresses in Oscillating Thoracic Arteries Reduce Circumferential Stresses and Stress Gradients
The purpose of this paper is to examine the eeects of residual stresses and strains in the oscillating arteries on the stress distribution in the vascular wall. We employ a static theory of large elastic deformations for orthotropic material (Chuong and Fung, 1986) with the acceleration term added to make the theory dynamic. We use the static elastic parameters of residual stresses in our analy...
متن کاملShear Stresses in Shock-compressed Covalent Solids
Shear stresses are the driving forces for the creation of both point and extended defects in crystals subjected to high pressures and temperatures. Recently, we observed anomalous elastic materials response in shock-compressed silicon and diamond in the course of our MD simulations and were able to relate this phenomenon to non-monotonic dependence of shear stress on uniaxial compression of the...
متن کاملCellular response to hyperosmotic stresses.
Cells in the renal inner medulla are normally exposed to extraordinarily high levels of NaCl and urea. The osmotic stress causes numerous perturbations because of the hypertonic effect of high NaCl and the direct denaturation of cellular macromolecules by high urea. High NaCl and urea elevate reactive oxygen species, cause cytoskeletal rearrangement, inhibit DNA replication and transcription, i...
