Metals are typically malleable and ductile, deforming under stress without cleaving. The sculpture challenges perception by distorting and deforming the surrounding architecture. Misalignment is accomplished by deforming of the material between the bolts. Furrows and ridges on the surface were caused by deforming ice. Forming is the operation of deforming a part in curved profile. Editing may involve denoising, deforming, or performing rigid transformations. The final effect is that of deflection, deforming and ricochet of a projectile. Some energy is lost in deforming the projectile and causing it to spin. To keep the lattice from deforming, a stress must be applied. This proof does not consider the possibility of the surface deforming as it moves. Informally, a Euclidean plane isometry is any way of transforming the plane without "deforming" it. Deforming a mug into an unusual shape is sometimes used. The cause and deforming mechanism underlying pes cavus is complex and not well understood. He can project psychokinetic concussion blasts capable of deforming steel at . The Nankai Trough is actively deforming and marks a region of seismic activity.
