Numerical modeling of soil behaviour under blast loading
Objectives:The work objectives for this contract are the
following:
The main objective of this contract is to improve numerical
modeling of the soil response under blast loading by
implementing constitutive material models in LS-DYNA for
different types of soil, by determining its parameters using
laboratory tests and in situ tests and then, by validating the
results with field experimental data. The level of degree of
water saturation and the rate of deformation will have to be
included in the soil constitutive models to be developed. Other
parameters such as level of compaction and particle size and
distribution may have to be included in order to improve soil
behaviour prediction under blast conditions.
Background
DRDC Valcartier often uses empirical model such as Westine model
to predict the deformation of simple geometries [Toussaint and
Bouamoul, 2010]. Measurements (displacements, velocities)
between experimental and numerical results on target are usually
compared and validated. However, when complex interactions
between the soil and structure must be modeled, or when the test
conditions are out of the empirical model tested conditions, a
better understanding of soil behaviour is required.
Constitutive soil models developed for static or quasi-static
loading are different than the ones developed to simulate soil
behaviour under high strain rate loading [Wang and Lu (2003), An
J. (2010)]. Predicting the soil behaviour under blast loading is
challenging because of the variety of parameters influencing its
behaviour. The soil loading conditions evolves from a pressure
wave propagation (near field) to a stress wave propagation (far
field) and is influenced by parameters such as the type of soil,
degree of water saturation, size of particles, particles
distribution, strain rate effect, mine depth of burial, etc. are
all parameters that may have to be considered. The variability
in experimental blast tests have shown the importance of
identifying these critical factors in order to get more
reproducibility in field trials and in order to develop good
constitutive soil models that will be used to predict mine blast
effects on structures. For example, Wang et Lu (2003), Wang et
al. (2004), Grujicic et al. (2008), Grujicic et al. (2009),
Pandurangan (2009), An (2010) and An et al. (2011) have
implemented factors such as the degree of water saturation and
the rate of deformation in their soil material models.

carryout 6 tasks.
Task 1: Literature review

Task 3: Implementation of the constitutive soil material models
in LS-DYNA
Task 4: Laboratory tests and in situ tests
Task 5: Constitutive soil model validation with FE simulation
Task 6: Reports and deliverables

Estimated funding available
The maximum funding available for the contract resulting from
the bid solicitation is $119,000.00 CAD (Goods and Services Tax
or the Harmonized Sales Tax extra, as appropriate). Bids valued
in excess of this amount will be considered non-responsive.
This disclosure does not commit Canada to pay the maximum
funding available.
Mandatory criteria
1. According to:
The contractor must implement the routines and sub-routines
developed for the soil constitutive models (for sandy-gravel
soil and clayed soil) and their corresponding relationships
(equation of state, strength model, damage/failure model,
erosion model) in LS-DYNA software.
The Bidder must demonstrated that LS-DYNA and related equipment
to use this software must be available and used by the bidder.
Point Rated Technical Criteria
Technical Proposal 50 points minimum 34 points
Expertise 45 points, minimum 25 points
Total: 95 points minimum 60 points.
Basis of Selection - Highest Rated Within Budget
To be declared responsive, a bid must:
(a) comply with all the requirements of the bid solicitation;
(b) meet all mandatory technical evaluation criteria;
(c) obtain the required minimum points for each group of
criteria a pass mark; and
(d) obtain the required minimum points overall for the technical
evaluation criteria which are subject to point rating.
Bids not meeting (a) or (b) or (c) or (d) will be declared non
responsive. The responsive bid with the highest number of
points will be recommended for award of a contract, provided
that the total evaluated price does not exceed the budget
available for this requirement. In the event that the highest
number of points is obtained by more than one responsive bid,
the responsive bid with the lowest evaluated price will be
recommended for award of a contract.
