13 maj 2020 · The constant deceleration approach assigns constant deceleration to the projectile from its impact with the target and ignores the entrance stage. This study shows that a two-stage simplified approach shows superior results compared to the one-stage approach.
2 lip 2019 · Constant deceleration approaches for penetration analysis of rigid projectile into concrete: Revisited
13 maj 2020 · This article reviews the one-stage constant deceleration approach and compares it with test data and with analytical and numerical models. This study clearly shows that concrete penetration cannot be presented by the proposed constant deceleration approach.
13 maj 2020 · This article reviews the one-stage constant deceleration approach and compares it with test data and with analytical and numerical models.
27 mar 2014 · As discussed in section 2.1, beside the soil water pressure or soil water content, the instantaneous evaporation process from a drying soil must be affected by such additional factors as gravity, thermal gradients and vapor transfer, and storage in the soil.
1 sie 2017 · The authors report that a constant S is obtained for each type of concrete, independent on the impact velocity. They found that the constant S decreases with increase of the uniaxial compressive strength: S = 21 for a 13.5 MPa strength, S = 12–14 for a 34–36 MPa and S = 7 for a strength of 96.7 MPa.
Calculate the GSI for a driver with a fastened seat belt who experiences a constant deceleration in a 30.0 miles per hour (13.4 m/s) collision and is stopped by a 1.0 m crumple zone. Need: GSI = _______ (a number)
