Problem Anchored Wall The vertical retaining wall of the figure below has a height of and it is pulled towards the sandy embankment through an anchor For the embankment material we have γ t =/m² and φ=30° The friction angle between the wall and the soil is δ= φ/2 Calculate the passive resistance exerted on the wall as

— The general contact model was adopted between the cutter and rock surface in the simulation Moreover the percussive process was analyzed without considering the static load; the compound impact load exerted on the cutter was decomposed into a horizontal impact load F H and a vertical impact load F V in ABAQUS

Examples of impact loads are loads from moving vehicles vibrating machinery or dropped weights In practice impact loads are considered equal to imposed loads that are incremented by some percentage called the impact factor Some building load impact factors are presented in Table The American Association of State Highway and

For materials without a well defined yield point it is typically defined using the % offset method in which a line parallel to the linear portion of the curve is drawn that intersects the x axis at a strain value of The point at which the line intersects the stress strain curve is designated as the yield point

3 — 3D printing requires more steps and considerations than you might think One of these important factors—often overlooked by designers and engineers—is part orientation also called build orientation How you orient your parts in the printer will play a significant role in delivering the final quality you want from additive components

The perception of materials is critical to our everyday interactions with objects in our environment All objects and substances are made up of materials and the visual identification of materials is a central part of object recognition Adelson 2001; Fleming 2014 For example we can rapidly distinguish whether objects such as flowers and fruit
